Completing the Square Formula is given as

ax2+bx+c⇒(x+p)2+constant

Solve x2x2 + 6x -2 = 0
Solution:

x2x2 + 6x – 2 = 0 can be written as (x+3)2(x+3)2 – 11 = 0

So, to solve the equation, take the square root of both sides. So (x+3)2(x+3)2 = 11

x+3=+11−−√11 or x+3=-11−−√11

x= -3+11−−√11 or x= -3 -11−−√11

11−−√11 =3.317

x = -3 +3.317 or x = -3 -3.317,

x=0.317 or x= -6.317
