Question

openstudy, what is the simplified form of y^2-3y+2/y^2+7y-18

Answer 1

First you unravel the quadratic equation... Do you know how to do that?

Answer 2

I tired to, but i Don't know if this is right...

(y-3) (y+2)
----------
(y+7 (y-18)

Answer 3

tried

Answer 4

You tried well but it's not right. Here, let me show you.
(y-2)(y-1) / (y+9)(y-2)

Answer 5

oh, okay. I see how you got that!

Answer 6

That's good. Do you know how to do the simplified form for this?

Answer 7

no, i do not.

Answer 8

You just cross out the (y-2) from top and bottom and leave the rest alone.
So you end up with
(y-1) / (y+9)

Answer 9

oh, i see! And would that be the final answer?

Answer 10

Yep

Answer 11

thank you!

Answer 12

No problem :)
