What Is a Quadratic Solver?
A quadratic solver finds the roots (x-values where the function equals zero) of any quadratic equation of the form ax² + bx + c = 0. It applies the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a, handling all three cases — two distinct real roots, one repeated root, and two complex conjugate roots (when the discriminant is negative).
Understanding the Discriminant
- Δ = b² - 4ac > 0: Two distinct real roots — the parabola crosses the x-axis twice
- Δ = 0: One repeated root — the parabola just touches the x-axis at its vertex
- Δ < 0: Two complex conjugate roots — the parabola never crosses the x-axis
Applications
Quadratic equations appear in projectile motion physics (finding when an object hits the ground), circuit analysis (solving for voltage or current), geometry (finding dimensions given area), and optimization problems in economics and engineering.
