The quadratic formula uses the coefficients of a trinomial, also known as a quadratic equation, to find the roots (i.e. the x-intercepts) of the equation.

The form of a quadratic equation is ax2 + bx + c. Use the boxes to input the a, b, and c values and determine the roots of the equation.

Quadratic formula: (-b ± √b2-4ac) / 2a
