Answer:


x=2,-3

Explanation:

Set
(x-2)(x+3)^2 equal to
0.


(x-2)(x-3)^22=0

Solve for
x.

If any individual factor on the left side of the equation is equal to
0, the entire expression will be equal to
0.


x-2=0\\(x+3)^2=0

Set the first factor equal to
0 and solve.

Set the first factor equal to
0.


x-2=0

Add
2 to both sides of the equation.


x=2

Set the next factor equal to
0 and solve.

Set the next factor equal to
0.


(x+3)^2=0

Set the
x+3 equal to
0.


x+3=0

Subtract
-3 from both sides of the equation.


x=-3

The final solution is all the values that make
(x-2)(x+3)^2=0 true.


x=2,-3
