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

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

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

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

Reorder the terms:
-6 + 2x = 2x(2 + x)
-6 + 2x = (2 * 2x + x * 2x)
-6 + 2x = (4x + 2x2)

Solving
-6 + 2x = 4x + 2x2

Solving for variable 'x'.

Combine like terms: 2x + -4x = -2x
-6 + -2x + -2x2 = 4x + 2x2 + -4x + -2x2

Reorder the terms:
-6 + -2x + -2x2 = 4x + -4x + 2x2 + -2x2

Combine like terms: 4x + -4x = 0
-6 + -2x + -2x2 = 0 + 2x2 + -2x2
-6 + -2x + -2x2 = 2x2 + -2x2

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

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

Ignore the factor -2.
Subproblem 1
Set the factor '(3 + x + x2)' equal to zero and attempt to solve:

Simplifying
3 + x + x2 = 0

Solving
3 + x + x2 = 0

Begin completing the square.

Move the constant term to the right:

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

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

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

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

The x term is x.  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.
x + 0.25 + x2 = -3 + 0.25

Reorder the terms:
0.25 + x + x2 = -3 + 0.25

Combine like terms: -3 + 0.25 = -2.75
0.25 + x + x2 = -2.75

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = -2.75

Can't calculate square root of the right side.
