Question

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

Answer 1

Square both sides then isolate the variable

Explanation:

Given:
`color(white)("XXX")sqrt(1-s)=2`

Squaring both sides:
`color(white)("XXX")1-s=4`

Subtract `1` from both sides
`color(white)("XXX")-s=3`

Multiply both sides by `(-1)`
`color(white)("XXX")s=-3`
