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


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

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

Reorder the terms:
-1 + 4x = 4x(-2 + x)
-1 + 4x = (-2 * 4x + x * 4x)
-1 + 4x = (-8x + 4x2)

Solving
-1 + 4x = -8x + 4x2

Solving for variable 'x'.

Combine like terms: 4x + 8x = 12x
-1 + 12x + -4x2 = -8x + 4x2 + 8x + -4x2

Reorder the terms:
-1 + 12x + -4x2 = -8x + 8x + 4x2 + -4x2

Combine like terms: -8x + 8x = 0
-1 + 12x + -4x2 = 0 + 4x2 + -4x2
-1 + 12x + -4x2 = 4x2 + -4x2

Combine like terms: 4x2 + -4x2 = 0
-1 + 12x + -4x2 = 0

Begin completing the square.  Divide all terms by
-4 the coefficient of the squared term: 

Divide each side by '-4'.
0.25 + -3x + x2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + -3x + -0.25 + x2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + -3x + x2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + -3x + x2 = 0 + -0.25
-3x + x2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
-3x + x2 = -0.25

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 = -0.25 + 2.25

Reorder the terms:
2.25 + -3x + x2 = -0.25 + 2.25

Combine like terms: -0.25 + 2.25 = 2
2.25 + -3x + x2 = 2

Factor a perfect square on the left side:
(x + -1.5)(x + -1.5) = 2

Calculate the square root of the right side: 1.414213562

Break this problem into two subproblems by setting 
(x + -1.5) equal to 1.414213562 and -1.414213562.

Subproblem 1

x + -1.5 = 1.414213562 Simplifying x + -1.5 = 1.414213562 Reorder the terms: -1.5 + x = 1.414213562 Solving -1.5 + x = 1.414213562 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
