Is this correct??

Hello

IS this correct? I have to perform the indicated operations and simplify

$$\frac{1}{x+2}+\frac{1}{x^2-4}-\frac{2}{x^2-x-2}$$

$$\frac{x^2+2x-5}{(x+2)(x-2)(x+1)}$$

Thanks

Shouldn't the numerator of the answer be: $x^2 - 2x - 5$?

Sorry I have made a typing mistake

its

$$\frac{x^2-2x-5}{(x+2)(x-2)(x+1)}$$

is this correct?

Yep, checks out with Mathematica, hehe, I'm so lazy. So yeah it's right.
