Chapter 11: Q 32 (page 1069)

In the following exercises, factor the greatest common factor from each polynomial.
$- 6 a^{3} b - 12 a^{2} b^{2} + 18 a b^{2}$

Short Answer

Expert verified

The given polynomial is factored as $- 6 a^{3} b - 12 a^{2} b^{2} + 18 a b^{2} = - 6 a b (a^{2} + 2 a b - 3 b)$

Step by step solution

Step 1. Given Information

Consider a polynomial $- 6 a^{3} b - 12 a^{2} b^{2} + 18 a b^{2}$ .

The objective is to factor the polynomial by factoring the greatest common factor.

Step 2. Factor the GCF

The GCF of three terms of the polynomial $- 6 a^{3} b, - 12 a^{2} b^{2}, 18 a b^{2}$ is $- 6 a b$ . So rewriting the polynomial terms with the product of GCF and then using the distributive property we get

$\begin{array}{rcl} - 6 a^{3} b - 12 a^{2} b^{2} + 18 a b^{2} & = & - 6 a b 路 a^{2} - 6 a b 路 2 a b + (- 6 a b) (- 3 b) \\ = & - 6 a b (a^{2} + 2 a b - 3 b) \end{array}$

Step 3. Check

To check we multiply the factors and we get

$\begin{array}{rcl} - 6 a b (a^{2} + 2 a b - 3 b) & = & - 6 a b 路 a^{2} + (- 6 a b) 路 2 a b + (- 6 a b) (- 3 b) \\ = & - 6 a^{3} b - 12 a^{2} b^{2} + 18 a b^{2} \end{array}$

And we get the given polynomial. So the factor is done correctly.
