Add or subtract and simplify if possible:

Question

2x + 9 -36
---- --- ---------
x+3 x-3 x^2-9

Answer 1

Don't try to "create" fractions in this format, the spacing comes out all wrong.

did you mean:

2x/(x+3) + 9/(x-3) - 36/(x^2 - 9) ??

if so, notice that x^2-9 = (x+3)(x-3) , so your LCD is
(x+3)(x-3)

give it a try
