Quadratic Equations Overview
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. Quadratic equations are equations of the form y = ax2 + bx + c or y = a(x – h)2 + k. The shape of the graph of a quadratic equation is a parabola.
Quadratic Equation Formula
The solution or roots of a quadratic equation are given by the quadratic formula: (α, β) = [-b ± √(b2 – 4ac)]/2a
α = (-b-√b2-4ac)/2a and β = (-b+√b2-4ac)/2a
| b2 – 4ac > 0 | Real and unequal |
| b2 – 4ac = 0 | Real and equal |
| b2 – 4ac < 0 | Unequal and Imaginary |
| b2 – 4ac > 0 (is a perfect square) | Real, rational, and unequal |
| b2 – 4ac > 0 (is a perfect square) | Real, irrational, and unequal |
| b2 – 4ac > 0 (is a perfect square and a or b is irrational) | Irrational |
