Quadratic Equations 
Quadratic Polynomials 
General Quadratic Equations is 
General Quadratic Polynomial is 
Solutions of quadratic equations are called its roots. 
Solutions of quadratic polynomials are called its zeroes. 
x^{2} – Sx + P = 0
Find the roots of
5x^{2}  6x  2 = 0 by the method of completing the square
Given equation is
5x^{2}  6x  2 = 0
D = b^{2}  4ac ⇒ D = (6)^{2}  4 x 5 x 2 = 36+40 = 76 > 0 ⇒ Roots are real and distinct ⇒ Roots of Q. E. are exists Now we apply method of completing the square as follows
Step (1) Make the coefficient of x^{2}
unity ( divide the equation by 5)
Step (2) Bring the constant term to the RHS
Step (3)
Step (4) Completing
the square and find the square root

Find the roots of 5x^{2}  6x  2 = 0 by the Quadratic Formula Given equation is 5x^{2}  6x  2 = 0 D = b2  4ac ⇒ D = (6)^{2}  4 x 5 x 2 = 36 + 40 = 76 > 0 ⇒ Roots are real and distinct ⇒ Roots of Q. E. are exists Now we apply the quadratic formula
