Mar 21, 2024 · Real roots of a polynomial equation are solutions that belong to the set of real numbers. In the context of quadratic equations like ax2+bx+c=0, real roots can be found using the quadratic formula: x = (−b ± b2−4ac) /2a. For example, consider the equation x2−4=0. The coefficients are a = 1, b = 0, and c = −4.
The number of roots of a polynomial equation is equal to its degree. So, a quadratic equation has two roots. Some methods for finding the roots are: Factorization method; Quadratic Formula; Completing the square method; All the quadratic equations with real roots can be factorized.

Real roots. The real roots are expressed as real numbers. Suppose a x 2 + b x + c = 0 is a quadratic equation and D = b 2 – 4 a c is the discriminant of the equation such that: If D = 0, then the roots of the equation are real and equal numbers. If D > 0, then the roots are real and unequal.
