solve this equation

Question

(1/(x+3)) - (x/(x²-9))=-(2/(x-3))

Answer 1

To figure this out, you need to find a common denominator for the left side of the equals sign. Consider factoring (x^2 - 9). It is (x+3)(x-3).

 

Now the left-most term only needs an (x-3), so multiply and divide it by (x-3). You will now have a common denominator. Combine the left side as a big fraction, then cross multiply, combine like terms, and find an answer.
