Pre-Algebra Examples

$\sqrt{9 x^{2} - 12 x}$

Step 1

Factor $3 x$ out of $9 x^{2}$ .

$\sqrt{3 x (3 x) - 12 x}$

Step 2

Factor $3 x$ out of $- 12 x$ .

$\sqrt{3 x (3 x) + 3 x (- 4)}$

Step 3

Factor $3 x$ out of $3 x (3 x) + 3 x (- 4)$ .

$\sqrt{3 x (3 x - 4)}$

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