Answer:
You have two variables, and only one condition. It means you have infinite solutions of the form . Technically correct, probably not what you want to know.
If you wanted to know if and where the RHS crosses the x axis, the points are the solution to
If you wanted the graph it's a parabola passing through the two points we just found, (0;-7), and with an axis of equation .
