Answer:

-2 and -4

Explanation:

When the quadratic equation equals 0, that means when y = 0.

By looking at the graph, whenever y = 0 is when the graph crosses the x-axis.

The graph crosses the x-axis at only two points:

(-4, 0) and (-2, 0)

So the solutions to the graph when -x^2 - 6x - 8 equals 0 is -2 & -4.

Hope it helps (●'◡'●)
