# Zeros and the Quadratic Formula

Sometimes you cannot find the zeros of a

quadratic function easily. To find the zeros of

y=ax^{2}+bx+c,

Substitute y =0 and solve for x . When a quadratic

equation is in standard form, you can use the

quadratic formula to solve this equation.

The solution of ax ^{2}+bx+c=0 are

So,

Or

A quadratic equation has one, two , or no solution.
