6 + -3x = 2x(-6 + 4x + -3x)

Combine like terms: 4x + -3x = 1x
6 + -3x = 2x(-6 + 1x)
6 + -3x = (-6 * 2x + 1x * 2x)
6 + -3x = (-12x + 2x2)

Solving
6 + -3x = -12x + 2x2

Solving for variable 'x'.

Combine like terms: -3x + 12x = 9x
6 + 9x + -2x2 = -12x + 2x2 + 12x + -2x2

Reorder the terms:
6 + 9x + -2x2 = -12x + 12x + 2x2 + -2x2

Combine like terms: -12x + 12x = 0
6 + 9x + -2x2 = 0 + 2x2 + -2x2
6 + 9x + -2x2 = 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
6 + 9x + -2x2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
-3 + -4.5x + x2 = 0

Move the constant term to the right:

Add '3' to each side of the equation.
-3 + -4.5x + 3 + x2 = 0 + 3

Reorder the terms:
-3 + 3 + -4.5x + x2 = 0 + 3

Combine like terms: -3 + 3 = 0
0 + -4.5x + x2 = 0 + 3
-4.5x + x2 = 0 + 3

Combine like terms: 0 + 3 = 3
-4.5x + x2 = 3

The x term is -4.5x.  Take half its coefficient (-2.25).
Square it (5.0625) and add it to both sides.

Add '5.0625' to each side of the equation.
-4.5x + 5.0625 + x2 = 3 + 5.0625
