Graph it. It's a parabola.
Then look for points of intersection.

There are two points of intersection.

(2,4)

Looks like x=-15 is the other intersection point.
use either function to calculate the y value.
y=x%5E2=%28-15%29%5E2=225
(-15,225)

Subtract it from both sides to get: 0+=+30+-+13x+-+x%5E2, or y+=+30+-+13x+-+x%5E2. Then graph it to get the solutions.
