Question

Factor to write an equivalent expression.(What is the Greatest Common Factor?).

−9x+15y

Answer 1

GCF is 3

Explanation:

Given the expression -9x + 15y

First, we need to find ther individual factors

-9x = -3 *3 * x

15y = 3 * 5 * y

Since 3 is common to both factors

−9x+15y = 3(-3x+5y)

Hence the GCF is 3
