Question

wirte this trinomal in factored form
7ypower2+2y-5

Answer 1

Okay, so to start, you're going to write

(7y -/+ __) and (y -/+__)

From there you find the factors of c, or in this case 5. Those are 5 and 1. Since it's a minus 5, you'll know that one of the numbers is going to be negative.

From there, you figure out which combo gives you a positive 2 when you add then together.

So the possible combos would be
(7y + 1) (y - 5)
(7y + 5) (y - 1)
(7y - 1) (y + 5)
(7y - 5) (y + 1)


One is right three are wrong.

Can you figure it out from there??
