Solution for 2(x+6)=-2x(x-4) equation: 


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

Reorder the terms:
2(6 + x) = -2x(x + -4)
(6 * 2 + x * 2) = -2x(x + -4)
(12 + 2x) = -2x(x + -4)

Reorder the terms:

12 + 2x = (-4 * -2x + x * -2x)
12 + 2x = (8x + -2x2)

Solving
12 + 2x = 8x + -2x2

Solving for variable 'x'.

Combine like terms: 2x + -8x = -6x
12 + -6x + 2x2 = 8x + -2x2 + -8x + 2x2

Reorder the terms:
12 + -6x + 2x2 = 8x + -8x + -2x2 + 2x2

Combine like terms: 8x + -8x = 0
12 + -6x + 2x2 = 0 + -2x2 + 2x2
12 + -6x + 2x2 = -2x2 + 2x2

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

Factor out the Greatest Common Factor (GCF), '2'.
2(6 + -3x + x2) = 0

Ignore the factor 2.

Subproblem 1
Set the factor '(6 + -3x + x2)' equal to zero and attempt to solve:

Simplifying
6 + -3x + x2 = 0

Solving
6 + -3x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-6' to each side of the equation.
6 + -3x + -6 + x2 = 0 + -6

Reorder the terms:
6 + -6 + -3x + x2 = 0 + -6

Combine like terms: 6 + -6 = 0
0 + -3x + x2 = 0 + -6
-3x + x2 = 0 + -6

Combine like terms: 0 + -6 = -6
-3x + x2 = -6

The x term is -3x.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3x + 2.25 + x2 = -6 + 2.25

Reorder the terms:
2.25 + -3x + x2 = -6 + 2.25

Combine like terms: -6 + 2.25 = -3.75
2.25 + -3x + x2 = -3.75

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = -3.75

Can't calculate square root of the right side.
