Finding x-intercepts:
Let y=0 and solve for x.
You could or should general solution for quadratic equation. Just follow the formula and solve for x in ; or factorize if possible.

Finding y-intercept:
Just let x=0 and solve for y. That will be your y-intercept.
This is not more than simple substitution, as in .
