Factor completely.

3y^2-3y-90

Step-by-step explanation:

First you would find 3y to the 2 power which would have a product of 9y. The little carrot looking symbole represents a power which in this case the power is 2. You are not multiplying 3 by 2 you are multiplying 3 two times which would give you a product of 9. Than you would subtract 3y from 9y which would give you a product of 6y. You would subtract these two numbers because they are like factors which means they have the same variable which in this case is y. Finally you would be left with 6y-90 and that would give you your answer, because 6y and 90 are not like factors therefore you can not subtract 6y from 90
