Simplify: $\displaystyle \frac{3}{(x + 4)(x - 2)} - \frac{2}{(x + 3)(x - 2)} $ $\displaystyle \frac{3(x + 3)(x - 2)}{(x + 4)(x - 2)(x + 3)} - \frac{2(x + 4)}{(x + 4)(x + 3)(x - 2)} $ Is this correct so far?

Your first step should be to do $\displaystyle \frac{3(x+3)-2(x+4)}{(x+4)(x-2)(x+3)}$ and it will simplify from here Paul
Hi, Thanks for your help, I never know what to multiply the numerator by as there are a lot of numbers in the denominator. Could you please explain this? Cheers.
