-15 + 3x + (-4 * -4 + 2x * -4) = -2x(x + -11)
-15 + 3x + (16 + -8x) = -2x(x + -11)

Reorder the terms:
-15 + 16 + 3x + -8x = -2x(x + -11)

Combine like terms: -15 + 16 = 1
1 + 3x + -8x = -2x(x + -11)

Combine like terms: 3x + -8x = -5x
1 + -5x = -2x(x + -11)

Reorder the terms:
1 + -5x = -2x(-11 + x)
1 + -5x = (-11 * -2x + x * -2x)
1 + -5x = (22x + -2x2)

Solving
1 + -5x = 22x + -2x2

Solving for variable 'x'.

Combine like terms: -5x + -22x = -27x
1 + -27x + 2x2 = 22x + -2x2 + -22x + 2x2

Reorder the terms:
1 + -27x + 2x2 = 22x + -22x + -2x2 + 2x2

Combine like terms: 22x + -22x = 0
1 + -27x + 2x2 = 0 + -2x2 + 2x2
1 + -27x + 2x2 = -2x2 + 2x2

Combine like terms: -2x2 + 2x2 = 0
1 + -27x + 2x2 = 0

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

Divide each side by '2'.
0.5 + -13.5x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -13.5x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -13.5x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -13.5x + x2 = 0 + -0.5
-13.5x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-13.5x + x2 = -0.5

The x term is -13.5x.  Take half its coefficient (-6.75).
Square it (45.5625) and add it to both sides.

Add '45.5625' to each side of the equation.
-13.5x + 45.5625 + x2 = -0.5 + 45.5625

Reorder the terms:
45.5625 + -13.5x + x2 = -0.5 + 45.5625

Combine like terms: -0.5 + 45.5625 = 45.0625
45.5625 + -13.5x + x2 = 45.0625
