In the realm of mathematics, specifically within algebra, polynomial factorization plays a crucial role. It is the process of breaking down a polynomial into a product of simpler polynomials, much like factoring integers into their prime factors. Understanding polynomial factorization is essential for simplifying algebraic expressions, solving equations, and analyzing functions. In this article, we will dissect several statements regarding polynomial factorization to determine their validity. We will delve into the techniques and principles involved in correctly factoring polynomials, ensuring a comprehensive understanding of the subject. This exploration will not only clarify the correct methods but also highlight common pitfalls and misconceptions that can arise during the factorization process. Accurately factoring polynomials is a foundational skill that underpins more advanced mathematical concepts, making its mastery indispensable for students and professionals alike.

To assess the truthfulness of the given statements, we must apply the principles of polynomial factorization. This involves identifying common factors, using the distributive property in reverse, and recognizing special patterns. Each statement presents a polynomial expression and a proposed factorization. Our task is to meticulously examine each factorization to determine if it accurately represents the original polynomial. This requires a step-by-step approach, ensuring that each term in the factored expression correctly corresponds to its counterpart in the original expression. The process involves not only factoring out common terms but also verifying the remaining expression within the parentheses. Incorrect factorization often results from overlooking a common factor or misapplying the distributive property. Therefore, a thorough and systematic approach is paramount in validating these statements. Through careful analysis, we can confidently identify the accurate factorizations and understand the underlying principles that govern them. This analytical journey will enhance our understanding of polynomial factorization, equipping us with the skills necessary to tackle more complex algebraic problems.

Statement 1: $6 m^2+18 m=6 m^2(1+3 m)$

Let's examine the first statement: $6 m^2+18 m=6 m^2(1+3 m)$. To determine its validity, we need to factor the left-hand side of the equation and compare it with the right-hand side. The given polynomial is $6m^2 + 18m$. Our primary goal is to identify the greatest common factor (GCF) of the terms $6m^2$ and $18m$. The GCF of the coefficients 6 and 18 is 6. For the variable terms, $m^2$ and $m$, the GCF is $m$. Therefore, the GCF of the entire polynomial is $6m$. Now, we factor out $6m$ from each term: $6m^2 + 18m = 6m(m + 3)$. Comparing this factored form with the right-hand side of the given equation, $6m^2(1 + 3m)$, we observe a significant difference. The correct factorization yields $6m(m + 3)$, while the statement proposes $6 m^2(1+3 m)$. To further illustrate the discrepancy, let's distribute the terms in the proposed factorization: $6m^2(1 + 3m) = 6m^2 + 18m^3$. This result is clearly not equal to the original polynomial, $6m^2 + 18m$. Therefore, the first statement is incorrect. The error lies in the incorrect factoring of the polynomial, specifically in not properly identifying and factoring out the common terms. This detailed analysis underscores the importance of meticulously factoring polynomials and verifying the results to ensure accuracy.

Statement 2: $15 m^3-6 m=3 m

(5 m^2-6 m)$

The second statement presents the equation $15 m^3-6 m=3 m(5 m^2-6 m)$. To verify this, we will factor the left-hand side of the equation and compare it to the right-hand side. The polynomial we are working with is $15m^3 - 6m$. We need to find the greatest common factor (GCF) of the terms $15m^3$ and $-6m$. The GCF of the coefficients 15 and -6 is 3. For the variable terms, $m^3$ and $m$, the GCF is $m$. Thus, the GCF of the polynomial is $3m$. Now, we factor out $3m$ from each term: $15m^3 - 6m = 3m(5m^2 - 2)$. Comparing this factored form with the right-hand side of the given equation, $3m(5m^2 - 6m)$, we can see a discrepancy. The correct factorization is $3m(5m^2 - 2)$, while the statement proposes $3m(5m^2 - 6m)$. To highlight the error, let's distribute the terms in the proposed factorization: $3m(5m^2 - 6m) = 15m^3 - 18m^2$. This result does not match the original polynomial, $15m^3 - 6m$. The mistake in the statement is that it incorrectly factored out the terms, leading to an incorrect expression inside the parentheses. The term $-6m$ should have been $-2$ after factoring out $3m$. Therefore, the second statement is also incorrect. This analysis reiterates the need for careful attention to detail when factoring polynomials, particularly in identifying and factoring out the GCF correctly.

Statement 3: $40 m^6-4=4(10 m^6-1)$

Now, let's evaluate the third statement: $40 m^6-4=4(10 m^6-1)$. To determine the validity of this statement, we need to factor the left-hand side of the equation and compare the result with the right-hand side. The polynomial expression we are considering is $40m^6 - 4$. The greatest common factor (GCF) of the terms $40m^6$ and $-4$ is 4. We factor out the GCF, 4, from the polynomial: $40m^6 - 4 = 4(10m^6 - 1)$. Now, let's compare this factored form with the right-hand side of the given equation, which is $4(10m^6 - 1)$. We observe that the factored form we obtained exactly matches the expression on the right-hand side of the equation. To further confirm this, we can distribute the 4 back into the parentheses: $4(10m^6 - 1) = 40m^6 - 4$. This result matches the original polynomial, $40m^6 - 4$, confirming that the factorization is correct. Therefore, the third statement is true. The polynomial $40m^6 - 4$ is correctly factored as $4(10m^6 - 1)$. This example highlights the importance of accurately identifying and factoring out the greatest common factor to correctly simplify polynomial expressions.

Statement 4: $32 m^4+12 m^3=4 m^3(8 m+3)$

Finally, let's analyze the fourth statement: $32 m^4+12 m^3=4 m^3(8 m+3)$. To assess its truthfulness, we will factor the left-hand side of the equation and compare it with the right-hand side. The given polynomial is $32m^4 + 12m^3$. We need to find the greatest common factor (GCF) of the terms $32m^4$ and $12m^3$. The GCF of the coefficients 32 and 12 is 4. For the variable terms, $m^4$ and $m^3$, the GCF is $m^3$. Therefore, the GCF of the entire polynomial is $4m^3$. Now, we factor out $4m^3$ from each term: $32m^4 + 12m^3 = 4m^3(8m + 3)$. Comparing this factored form with the right-hand side of the given equation, $4m^3(8m + 3)$, we observe that they are exactly the same. To further verify this, let's distribute the terms in the factored form: $4m^3(8m + 3) = 32m^4 + 12m^3$. This result matches the original polynomial, confirming that the factorization is correct. Thus, the fourth statement is true. The polynomial $32m^4 + 12m^3$ is accurately factored as $4m^3(8m + 3)$. This analysis demonstrates the importance of correctly identifying and factoring out the greatest common factor, ensuring that the factorization accurately represents the original polynomial expression.

In conclusion, through a detailed examination of each statement, we have identified the true and false factorizations of the given polynomial expressions. Polynomial factorization is a fundamental skill in algebra, requiring a methodical approach to ensure accuracy. The key lies in identifying the greatest common factor (GCF) and correctly applying the distributive property in reverse. Statements 3 and 4, $40 m^6-4=4(10 m^6-1)$ and $32 m^4+12 m^3=4 m^3(8 m+3)$, were found to be true, demonstrating correct factorization. Conversely, statements 1 and 2, $6 m^2+18 m=6 m^2(1+3 m)$ and $15 m^3-6 m=3 m(5 m^2-6 m)$, were incorrect due to errors in the factorization process. Mastering polynomial factorization is essential for simplifying algebraic expressions, solving equations, and tackling more advanced mathematical concepts. This analysis underscores the importance of meticulous attention to detail and a thorough understanding of the underlying principles of factorization. By consistently applying these principles, one can confidently navigate the complexities of polynomial factorization and ensure accurate results.
