Answer

$$\frac{6x-20}{\left(x+5\right)\left(x-5\right)}$$

Work Step by Step

Ensuring that we have like denominators and then attempting to simplify, we find: $$\frac{4\left(x-5\right)}{\left(x+5\right)\left(x-5\right)}+\frac{2x}{\left(x+5\right)\left(x-5\right)}\\ \frac{4\left(x-5\right)+2x}{\left(x+5\right)\left(x-5\right)}\\ \frac{6x-20}{\left(x+5\right)\left(x-5\right)}$$
