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
