Solution for 24x=(5x+1)(x-1) equation:


Simplifying
24x = (5x + 1)(x + -1)

Reorder the terms:
24x = (1 + 5x)(x + -1)

Reorder the terms:
24x = (1 + 5x)(-1 + x)

Multiply (1 + 5x) * (-1 + x)
24x = (1(-1 + x) + 5x * (-1 + x))
24x = ((-1 * 1 + x * 1) + 5x * (-1 + x))
24x = ((-1 + 1x) + 5x * (-1 + x))
24x = (-1 + 1x + (-1 * 5x + x * 5x))
24x = (-1 + 1x + (-5x + 5x2))

Combine like terms: 1x + -5x = -4x
24x = (-1 + -4x + 5x2)

Solving
24x = -1 + -4x + 5x2

Solving for variable 'x'.

Reorder the terms:
1 + 24x + 4x + -5x2 = -1 + -4x + 5x2 + 1 + 4x + -5x2

Combine like terms: 24x + 4x = 28x
1 + 28x + -5x2 = -1 + -4x + 5x2 + 1 + 4x + -5x2

Reorder the terms:
1 + 28x + -5x2 = -1 + 1 + -4x + 4x + 5x2 + -5x2

Combine like terms: -1 + 1 = 0
1 + 28x + -5x2 = 0 + -4x + 4x + 5x2 + -5x2
1 + 28x + -5x2 = -4x + 4x + 5x2 + -5x2

Combine like terms: -4x + 4x = 0
1 + 28x + -5x2 = 0 + 5x2 + -5x2
1 + 28x + -5x2 = 5x2 + -5x2

Combine like terms: 5x2 + -5x2 = 0
1 + 28x + -5x2 = 0

Begin completing the square.  Divide all terms by
-5 the coefficient of the squared term: 

Divide each side by '-5'.
-0.2 + -5.6x + x2 = 0

Move the constant term to the right:

Add '0.2' to each side of the equation.
-0.2 + -5.6x + 0.2 + x2 = 0 + 0.2

Reorder the terms:
-0.2 + 0.2 + -5.6x + x2 = 0 + 0.2

Combine like terms: -0.2 + 0.2 = 0.0
0.0 + -5.6x + x2 = 0 + 0.2
-5.6x + x2 = 0 + 0.2

Combine like terms: 0 + 0.2 = 0.2
-5.6x + x2 = 0.2

The x term is -5.6x.  Take half its coefficient (-2.8).
Square it (7.84) and add it to both sides.

Add '7.84' to each side of the equation.
-5.6x + 7.84 + x2 = 0.2 + 7.84

Reorder the terms:
7.84 + -5.6x + x2 = 0.2 + 7.84

Combine like terms: 0.2 + 7.84 = 8.04
7.84 + -5.6x + x2 = 8.04

Factor a perfect square on the left side:
(x + -2.8)(x + -2.8) = 8.04

Calculate the square root of the right side: 2.835489376
