Finding Solutions of Quadratic Equations:

There are three method to find solution of quadratic equation.

(A)  By Factorisation Method:

(B)  By Completing Square Method:

(C)  By Quadratic Formula: 

 

Factorisation Method: In this method the middle term is seperated into two part and then there is found the two common factors. 

 

(B) Completing Square Method:

      (i) Using Division

      (ii) Using Multiplication

      (i) Using Division:

     Example 1:

      Solving quadratic equation ax2 + bx + c = 0 for x

      Dividing the equation by a.

(i) Using Division

Example 2: Find the roots of the equation 2x2 – 5x + 3 = 0 by the method of completing the square.

Solution:

(ii) Using multiplication:

Example 2. Solve for x using complete squaring method 2x2 + 3x - 7 = 0;
