The values a=1, b=-5,c=6 should return x=3, x=2.  The default values for a, b, and c are filled in to allow you to easily test the quadratic equation calculator.  If the results are 3 and 2, then the calculator is working!

Quadratic Equation Calculator Instructions

Replace the default values for a, b, and c with the values from the quadratic equation that you are solving.

You may need to rearrange your equation into this form:
ax² + bx + c = 0

For example, you can write a quadratic equation as: 1x² -5x + 6 =0
In this example, a=1, b= -5, and c=6.

Enter your values for a, b, and c into the calculator and click "Compute".  The two solutions for x will be calculated using the quadratic formula.
