How to Calculate Quadratic Formula

Solve any quadratic equation ax² + bx + c = 0.

The Formula

x = (-b ± √(b²-4ac)) / 2a

The quadratic formula formula uses the mathematical relationship: x = (-b ± √(b²-4ac)) / 2a. Each variable in the formula represents a measurable quantity that affects the final result.

Step-by-Step Method

  1. 1Identify all input values needed for the quadratic formula calculation.
  2. 2Substitute your known values into the formula: x = (-b ± √(b²-4ac)) / 2a.
  3. 3Perform the arithmetic operations in the correct order (PEMDAS/BODMAS).
  4. 4Check that your result has the correct units and is within a reasonable range.
  5. 5Verify using the interactive Quadratic Formula Calculator to confirm your answer.
