2x(x+1)=4x-6

Solution for 2x(x+1)=4x-6 equation:

Simplifying
2x(x + 1) = 4x + -6

Reorder the terms:
2x(1 + x) = 4x + -6
(1 * 2x + x * 2x) = 4x + -6
(2x + 2x2) = 4x + -6

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

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

Solving for variable 'x'.

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

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

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

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

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

Factor out the Greatest Common Factor (GCF), '2'.
2(3 + -1x + x2) = 0

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

Simplifying
3 + -1x + x2 = 0

Solving
3 + -1x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -1x + -3 + x2 = 0 + -3

Reorder the terms:
3 + -3 + -1x + x2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1x + x2 = 0 + -3
-1x + x2 = 0 + -3

Combine like terms: 0 + -3 = -3
-1x + x2 = -3

The x term is -1x.  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.
-1x + 0.25 + x2 = -3 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -3 + 0.25

Combine like terms: -3 + 0.25 = -2.75
0.25 + -1x + 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.
