Chapter 5 - Section 5.5 - The Greatest Common Factor and Factoring by Grouping - Exercise Set - Page 296: 91

Answer

$9(5 - x) + y(5 - x)$ involves a sum of $9(5 - x)$ and $y(5 - x)$ therefore it is not a factored form of $45-9x+5y-xy$

Work Step by Step

RECALL: Factoring means writing as a polynomial as a product. $9(5 - x) + y(5 - x)$ involves a sum of $9(5 - x)$ and $y(5 - x)$ therefore it is not a factored form of $45-9x+5y-xy$
