10th Class Mathematics Quadratic Equations Introduction

      Introduction

In previous chapter we have studied about the polynomials. Quadratic equation is also a type of polynomial of degree two. The most general form of the quadratic equation is , where a, b, c are the coefficients. Solving the quadratic equation in general form has been worked out by some of the ancient mathematicians. In fact, Brahmagupta gave an explicit method to solve the quadratic equations. Later Sridharacharya derived special formulae for solving the quadratic equations known as the quadratic formula. One of the most prominent methods used in olden days mathematics for solving the quadratic equation was given by Bhaskar-11 for solving the quadratic equation by the completing square method.
