Doing on paper is easier. Try this approach.

Using standard form, , your vertex gives you:

The y intercept given allows you this relation:

What is the equation for the described parabola?

All you do next is just solve this for x using uncomplicated algebra steps with letting y=0.
Solve for x in .
