What 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)

Okay I understand it now I have to make them have the same denominators so I multiply 1/C by the numerator and denominator by C2 so it would be C2/(C2*C) and the other part is 1/C2 times C which would be C/(C2*C) which would make the problem 1/C1= C2-C/(C2*C) what do I do next?
