$\frac{x^{3} + 2 x^{2}}{3 x^{2} - 1}$

Step 1

Factor $x^{2}$ out of $x^{3}$ .

$\frac{x^{2} x + 2 x^{2}}{3 x^{2} - 1}$

Step 2

Factor $x^{2}$ out of $2 x^{2}$ .

$\frac{x^{2} x + x^{2} \cdot 2}{3 x^{2} - 1}$

Step 3

Factor $x^{2}$ out of $x^{2} x + x^{2} \cdot 2$ .

$\frac{x^{2} (x + 2)}{3 x^{2} - 1}$

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