Problem:

a^2-9 a^2-3a

----- * --------

a^2 a^2+a-12

What I Got:

3-3a

----

a-4

*Please Check My Work.*

Nope.

factor the denominator to a^2(a+4)(a-3)

The last factor divides out in the numerattor (second term factors to a(a-3). The a in the numerator reduces the denominaor a^2 term

I lost you afterthe last factor divides out the numerator.Which one?

In the numerator, either term will give you a-3 when factored.

So then:

3(a-3)

------

a(a+4)

Did you get your answer yet? Do you understand now?

No.-Can you help me please Mack.?

Margie,do you needy helpy?Do you speak espanol?

¿Sí, hablo español por qué?
