Given the equation

[tex]\sqrt[]{2w+8}=-w[/tex]

To solve the question, we will follow the steps below:

Step 1: square both sides

[tex]2w+8=(-w)^2[/tex]

Step 2: Simplify the expression

[tex]2w+8=w^2[/tex][tex]w^2-2w-8=0[/tex]

simplifying further

[tex](w+2)(w-4)=0[/tex]

Finding the zeros gives

[tex]\begin{gathered} w=-2\text{ } \\ or \\ w=4 \end{gathered}[/tex]

Hence

The solutions are: -2,4
