Applications Outline Quadratic Equations Solving Quadratic Equations The Discriminant Consider a quadratic equation ax 2 + bx + c = 0. The expression b 2 − 4ac is called the discriminant. The equation ax 2 + bx + c = 0 has: 1 2 3 Two real number solutions if b 2 − 4ac > 0. One real number solutions if b 2 − 4ac = 0. Two complex number solutions if b 2 − 4ac < 0. The complex solutions come in conjugate pairs. Example...
