Question

Factor the expression 28r + 42s -35

Answer 1

7(4r + 6r - 5)

Explanation:

Answer 2

First, find the GCF of 28, 42, and -35. When we use the ladder technique, we have: GCF(28, 42, -35) = 7. We know 7 * 4 is 28, 7 * 6 is 42, 7 * -5 is -35. So, we have the following result:
7(4r + 6r - 5)
We can't factor anymore.
