Question

Factor.
8 + 7y - y^2

Answer 1

(y-8)(y+1)

Answer 2

That's only when you move everything to the otherside when you make that equation equal to zero.

Answer 3

\[(8-y)(1+y)\]

Answer 4

Looks the same but you don't get the -y^2

Answer 5

Definitely not the same, but @Azteck is right.

Answer 6

And when you expand @musiclover101 's factored equation, you will get y^2-7y-8 instead of your above equation.

Answer 7

sorry -(y-8)(y+1)

Answer 8

So when you put it on the other side it turns to y^2 - 7y - 8? How does it do this again? I forgot.

Answer 9

When you take out the minus sign.

Answer 10

-(y^2-7y-8)

Answer 11

Oh alright, thank you!
