# How do you solve x^2 – 36 = 0?

Apr 21, 2018

$x = \pm 6$

#### Explanation:

$\text{isolate "x^2" by adding 36 to both sides of the equation}$

$\Rightarrow {x}^{2} = 36$

$\textcolor{b l u e}{\text{take the square root of both sides}}$

$\Rightarrow x = \pm \sqrt{36} \leftarrow \textcolor{b l u e}{\text{note plus or minus}}$

$\Rightarrow x = \pm 6 \text{ is the solution}$
