Quadratic Equation Solver


Below you can find a quadratic equation solver developed on a simple spreadsheet. It uses the known formula to calculate the roots (real and complex) of a quadratic expression.

If you have

ax2 + bx + c = 0

you can solve for x using

quadratic formula

Example 1

 Example 2
 If you have:

 a = 1, b = 4 and c = 3

 you'll get:

 x1 = -1
 x2 = -3
   If you have:

  a = 3, b = 4 and c = 5

  you'll get:

  x1 = -0.6667 + 1.1055i
  x2 = -0.6667 - 1.1055i


You have to use the edit button to make the spreadsheet work. You can reload this page (using your navigator buttons) to start from scratch.
