How a Quadratic Equation Solver Works
The solver follows a systematic process:
- Accepts coefficients a, b, and c
- Calculates the discriminant
- Determines the nature of the roots
- Applies the quadratic formula
- Displays the final solutions
The discriminant is a key part of solving quadratic equations:
The value of the discriminant determines whether the equation has:
- Two distinct real roots
- One repeated real root
- Two complex roots
Types of Solutions in Quadratic Equations
Two Real Roots
When the discriminant is greater than zero, the equation has two distinct real solutions.
Example:
x² - 5x + 6 = 0
Roots:
- x = 2
- x = 3
One Repeated Root
When the discriminant equals zero, both roots are identical.
Example:
x² - 4x + 4 = 0
Root:
- x = 2
Complex Roots
When the discriminant is less than zero, the roots contain imaginary numbers.
Example:
x² + 4x + 5 = 0
Roots:
- x = -2 + i
- x = -2 - i
