About This Calculator
This calculator solves quadratic equations of the form ax² + bx + c = 0
using the quadratic formula. It calculates the roots based on the discriminant (D = b² - 4ac
) and displays both real and complex roots.
How to Use
- Enter the coefficients a, b, and c of the quadratic equation.
- Click "Calculate" to compute the roots.
- The calculator displays the roots and the steps involved in the calculation.
Frequently Asked Questions
What if the discriminant is negative?
If the discriminant is negative, the equation has two complex conjugate roots.
What does a discriminant of zero mean?
A discriminant of zero means the equation has exactly one real root (a repeated root).
Why can't coefficient a be zero?
If a is zero, the equation is not quadratic but linear, and the quadratic formula does not apply.
