Standard form of quadratic equation

First combine all the like terms in the quadratic equation.

Secondly, degree of each term must drop from left to right starting from 2.

In our videos, you will study quadratic equations, and various ways of finding their roots.A quadratic equations can be solved by any one the given methods (i)Method of completing the square (ii)Factoring quadratic equation (iii) Quadratic Formula.

Here, in this video, we solve some quadratic equations using completing the square method which is based on using identity (a+b)^2.

Later you will also see some applications of quadratic equations in daily life situation.We solve word problems on quadratic equations
