Homework Help: Algebra

Posted by Sam on Friday, January 4, 2008 at 1:11am.

I have the answer, but don't know the procedure.

The question is:

Find the values of C and D if
c/(x-2) + D/(x+1) = 6x/(x^2-x-2)

The answers are: C= 4, D=2


HERE IS MY WORK:
Well, I know that we can add the left side and the denominators become the same. So, the new equations becomes:

c(x+1)+ D(x-2) = 6x

but, how do you go from here to find the values of c and d?
