$\frac{1}{x \cdot x + x}$

Step 2

Raise $x$ to the power of $1$ .

$\frac{1}{x \cdot x + x^{1}}$

Step 3

Factor $x$ out of $x^{1}$ .

$\frac{1}{x \cdot x + x \cdot 1}$

Step 4

Factor $x$ out of $x \cdot x + x \cdot 1$ .

$\frac{1}{x (x + 1)}$

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