QUADRATIC EQUATION: Introduction

In this post we will be going to study about quadratic equations.

Quadratic equations are those equations which have overall degree to be 2.

The general form for any quadratic equation in x is -

ax² + bx + c = 0 , where a ≠ 0

The graph of this kind of equations are parabolas.

The equations has degree two hence it will have atmost two real roots.

What are roots?

Roots or zeroes are the values of x for which the polynomial P(x) = ax² + bx + c becomes equal to zero.

We should be very careful about the fact that a quadratic equation has maximum of two real roots.

There are three four ways to find the roots of a quadratic equation which we will learn in upcoming posts.

1. Middle term splitting.

2. Completing the square.

3. Using Sridharacharya Formula or Quadratic formula.

4. A differeent way.(by Po-Shen Loh)
