Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -1x + -6 + x2 = 0 + -6

Reorder the terms:
6 + -6 + -1x + x2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -1x + x2 = 0 + -6
-1x + x2 = 0 + -6

Combine like terms: 0 + -6 = -6
-1x + x2 = -6

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = -6 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -6 + 0.25

Combine like terms: -6 + 0.25 = -5.75
0.25 + -1x + x2 = -5.75

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = -5.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
