A quadratic polynomial of the form ax² + bx + c, where a ≠ 0 and a, b, c are real numbers, is called a quadratic equation when ax² + bx + c = 0. Here a and b are the coefficients of x² and x respectively and ‘c’ is a constant term.

Quadratic formula of equation ax² + bx + c is Here:

Rules:

If D = 0 ⇒ The roots are Real and Equal.

If D > 0 ⇒ The two roots are Real and Unequal.

If D < 0 ⇒ No Real roots exist.
