Answer
$$ x=-2.5,2$$
Work Step by Step
To solve an equation set equal to zero using a graph, we see where the graph intersects the x-axis. Thus, we can use the reverse method, solving the equation by setting it equal to zero to see what the x-intercepts are. Doing this, we find:
$$ 0=2x^2+x-10 \\ 0=\left(x-2\right)\left(2x+5\right) \\ x=-2.5,2$$
