How do you solve sqrt (1 - s) = 2?

Square both sides then isolate the variable

Explanation:

Given:
$\textcolor{w h i t e}{\text{XXX}} \sqrt{1 - s} = 2$

Squaring both sides:
$\textcolor{w h i t e}{\text{XXX}} 1 - s = 4$

Subtract $1$ from both sides
$\textcolor{w h i t e}{\text{XXX}} - s = 3$

Multiply both sides by $\left(- 1\right)$
$\textcolor{w h i t e}{\text{XXX}} s = - 3$
