4-96.

Solve each equation for $x$ (that is, put it in $x = \text{____}$ form).

1. $y = 2\left(x − 17\right)^{2}$

Divide both sides by 2.

$(\textit{x}-17)^{2}= \frac{ \textit{y} }{2 }$

Now find the square root of both sides.

$\textit{x}-17=\pm \sqrt{ \frac{ \textit{y} }{2 } }$

Now finish solving.

$\textit{x}=\pm \sqrt{ \frac{ \textit{y} }{2 } } +17$

1. $y + 7 = \sqrt [ 3 ] { x + 5 }$

Raise both sides of the equation to the 3rd power, then subtract to isolate x. It is not necessary to expand $\left(x + 3\right)^{3}$.
