Factor 2ay-6a+15-5y

$2 a y - 6 a + 15 - 5 y$

Step 1

Regroup terms.

$- 6 a + 2 a y + 15 - 5 y$

Step 2

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(- 6 a + 2 a y) + 15 - 5 y$

Factor out the greatest common factor (GCF) from each group.

$2 a (- 3 + y) - 5 (- 3 + y)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $- 3 + y$ .

$(- 3 + y) (2 a - 5)$
