NCERT · Class 10 · Mathematics · Quadratic EquationsWrite the quadratic formula (Sridharacharya formula) for solving a quadratic equation.
Step-by-Step Solution
The quadratic formula, also famously known as the Sridharacharya formula in Indian mathematics, is used to find the roots of any given quadratic equation in the standard form ax² + bx + c = 0. The complete mathematical expression for this formula is x = (-b ± √(b² - 4ac)) / (2a), provided that the leading coefficient 'a' is not equal to zero. This formula is universally applicable and can always give the roots, whether they are rational, irrational, or even complex numbers.
