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

00:02 Q1 Find the roots of the following quadratic equations, if they exist, by the method of
completing the square:
Q1 (i) 2x^2– 7 x + 3 = 0
01:34 add Square of half of coefficient of x
04:12 Obtain roots of quadratic equation
05:10 Q1 (ii) 2x^2 + x – 4 = 0
05:28 Find Discriminant of Quadratic Equation
06:30 add Square of half of coefficient of x
08:44 find roots of quadratic equation.
