$\frac{x}{x - 5} \cdot \frac{2 x}{x + 4}$

Step 1

Multiply

$\frac{x}{x - 5}$ by

$\frac{2 x}{x + 4}$ .

$\frac{x (2 x)}{(x - 5) (x + 4)}$

Step 2

Raise

$x$ to the power of

$1$ .

$\frac{2 (x^{1} x)}{(x - 5) (x + 4)}$

Step 3

Raise

$x$ to the power of

$1$ .

$\frac{2 (x^{1} x^{1})}{(x - 5) (x + 4)}$

Step 4

Use the power rule

$a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\frac{2 x^{1 + 1}}{(x - 5) (x + 4)}$

Step 5

Add

$1$ and

$1$ .

$\frac{2 x^{2}}{(x - 5) (x + 4)}$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
