How To Find X And Y Intercepts Of A Quadratic Function References. The solutions of a quadratic equation of the form a x 2 + b x + c = 0 are given by the quadratic formula. That point is the x intercept.

To remove the radical on the left side of the equation, cube both sides of the equation. For a quadratic equations which is in the form. 0 = a (−2) 2 + b (−2) + c = 4 a − 2 b + c 3 x 2 + 5 x − 2 = 0 3 x 2 + 5 x − 2 = 0.
