Question

(t+2)^2=4

Answer 1

take a square root on both sides.

\[\sqrt{(t+2)^2} = \sqrt4\]

Answer 2

\[t + 2 = \pm 2\]

Answer 3

\(\Large \color{purple}{\rightarrow t + 2 = \pm2 }\)
\(\Large \color{purple}{\rightarrow t = 0 }\) or \(\Large \color{purple}{t = -4 }\)

Answer 4

therefore,

t +2 = 2 t + 2 = -2
