4a^2/(a-b)-(4b^2-8ab)/(b-a)

I have the answer as 4(a+b)^2/(a-b)

or should it be 4(a-b)^2/(a-b)

**bobpursley**, Sunday, October 12, 2008 at 4:23pmjust the numerator..

4a^2-8ab + 4b^2, right?

4(a-b)^2

Now does that reduce with the denominator?

**Shawn**, Sunday, October 12, 2008 at 4:37pmWhat about

4a^2/(a-b)-(4b^2-8ab)/(b-a)

I thought that you would multiple the second part of the equation by -1

-(4b^2-8ab)/(b-a)

to get the common LCD of a-b

So I thought the equation would be 4a^2/(a-b) + (4b^2 + 8ab)/(a-b)

I have the answer as 4(a+b)^2/(a-b)
