Answer 1

ANSWER :

The values of x are -8 and 8

EXPLANATION :

From the problem, we have the equation :

$x^2-47=17$

Add 47 to both sides :

$\begin{gathered} x^2-47+47=17+47 \\ x^2=64 \end{gathered}$

Take the square root of both sides :

$\begin{gathered} \sqrt{x^2}=\sqrt{64} \\ x=\pm8 \end{gathered}$
