Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
6 + -6x + x2 = 0

Move the constant term to the right:

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

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

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

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

The x term is -6x.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6x + 9 + x2 = -6 + 9

Reorder the terms:
9 + -6x + x2 = -6 + 9

Combine like terms: -6 + 9 = 3
9 + -6x + x2 = 3

Solving
-3 + x = 1.732050808

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.
-3 + 3 + x = 1.732050808 + 3

Combine like terms: -3 + 3 = 0
0 + x = 1.732050808 + 3
x = 1.732050808 + 3

Combine like terms: 1.732050808 + 3 = 4.732050808
x = 4.732050808

Simplifying
x = 4.732050808

Subproblem 2
x + -3 = -1.732050808

Simplifying
x + -3 = -1.732050808

Reorder the terms:
-3 + x = -1.732050808

Solving
-3 + x = -1.732050808

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.
-3 + 3 + x = -1.732050808 + 3

Combine like terms: -3 + 3 = 0
0 + x = -1.732050808 + 3
x = -1.732050808 + 3

Combine like terms: -1.732050808 + 3 = 1.267949192
x = 1.267949192
