Activity overview:

Quadratic formula | Solve word problems on Quadratic equations
http://www.learncbse.in/ncert-class-10-math-solutions/

In this video, 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.
Quadratic Formula is derived from Method of completing the square.To find roots of any quadratic equation by Quadratic Formula,we first need to find the Discriminant of quadratic equation.If Discriminant less than zero no real roots exist for given quadratic equation.If Discriminant is greater than zero, real roots exist.If Discriminant is zero then roots of quadratic equation are equal.

Solve the equation by Quadratic formula.
Steps to solve Word Problems:
Step 1:Read the problem carefully to know what is given and what to find out.
Step 2:Denote the unknown by a small letter like z, p etc.
Step 3:From the given condition, frame the quadratic equation Involving the unknown.
Step 4:Solve the equation by Quadratic formula.
