x2 – Sx + P = 0
Find the roots of
5x2 - 6x - 2 = 0 by the method of completing the square
Given equation is
5x2 - 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 method of completing the square as follows
Step (1) Make the coefficient of x2
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
