- View the results below and the chart for visual representation.
Formula & Methodology
The calculator uses the quadratic formula to find the zeroes:
x = [-b ± sqrt(b^2 - 4ac)] / (2a)
Real-World Examples
Example 1: x^2 – 5x + 6
Zeroes: x = 2, 3
Example 2: 2x^2 + 3x – 1
Zeroes: x = -1, -0.5
Example 3: x^2 – 10x + 25
Zeroes: x = 5 (double root)
