$x=-2$ and $x=-4$

Whenever you want to solve a function using a graph, you want to focus on the x-intercepts (which are the roots of the function). Let's graph this:

graph{-2(x+3)^2+2 [-9.956, 4.09, -3.04, 3.984]}

As you can see, the graph passes through the x-axis at $(-2,0)$ and $(-4,0)$ . Therefore, the roots of the function are $x=-2$ and $x=-4$
