6(2x-1)=x[x-3(6-3x)+2x]

Solution for 6(2x-1)=x[x-3(6-3x)+2x] equation:

Simplifying
6(2x + -1) = x[x + -3(6 + -3x) + 2x]

Reorder the terms:
6(-1 + 2x) = x[x + -3(6 + -3x) + 2x]
(-1 * 6 + 2x * 6) = x[x + -3(6 + -3x) + 2x]
(-6 + 12x) = x[x + -3(6 + -3x) + 2x]

-6 + 12x = x[-18 + 12x]
-6 + 12x = [-18 * x + 12x * x]
-6 + 12x = [-18x + 12x2]

Solving
-6 + 12x = -18x + 12x2

Solving for variable 'x'.

Combine like terms: 12x + 18x = 30x
-6 + 30x + -12x2 = -18x + 12x2 + 18x + -12x2

Reorder the terms:
-6 + 30x + -12x2 = -18x + 18x + 12x2 + -12x2

Combine like terms: -18x + 18x = 0
-6 + 30x + -12x2 = 0 + 12x2 + -12x2
-6 + 30x + -12x2 = 12x2 + -12x2

Combine like terms: 12x2 + -12x2 = 0
-6 + 30x + -12x2 = 0

Factor out the Greatest Common Factor (GCF), '6'.
6(-1 + 5x + -2x2) = 0

Ignore the factor 6.
Subproblem 1
Set the factor '(-1 + 5x + -2x2)' equal to zero and attempt to solve:

Simplifying
-1 + 5x + -2x2 = 0

Solving
-1 + 5x + -2x2 = 0

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

Divide each side by '-2'.
0.5 + -2.5x + x2 = 0

Move the constant term to the right:

Add '-0.5' to each side of the equation.
0.5 + -2.5x + -0.5 + x2 = 0 + -0.5

Reorder the terms:
0.5 + -0.5 + -2.5x + x2 = 0 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + -2.5x + x2 = 0 + -0.5
-2.5x + x2 = 0 + -0.5

Combine like terms: 0 + -0.5 = -0.5
-2.5x + x2 = -0.5

The x term is -2.5x.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5x + 1.5625 + x2 = -0.5 + 1.5625

Reorder the terms:
1.5625 + -2.5x + x2 = -0.5 + 1.5625

Combine like terms: -0.5 + 1.5625 = 1.0625
1.5625 + -2.5x + x2 = 1.0625

Factor a perfect square on the left side:
(x + -1.25)(x + -1.25) = 1.0625

Calculate the square root of the right side: 1.030776406

Break this problem into two subproblems by setting 
(x + -1.25) equal to 1.030776406 and -1.030776406.
