Factor the expression.

40y + 15

5 (8y + 3)

Step-by-step explanation:

First, find the GCF (greatest common factor) of 40 and 15, since to factor something, you need to find out what is common between the terms.

You can divide 40 into 2 x 2 x 2 x 5

and 15 into 3 x 5.

The greatest number that is common between both numbers is 5.

Therefore, you can factor the 5 out:

5 (40/5y + 15/5) =

5 (8y + 3)
