Solution for (2x-1)(2x+1)=10x equation:


Simplifying
(2x + -1)(2x + 1) = 10x

Reorder the terms:
(-1 + 2x)(2x + 1) = 10x

Reorder the terms:
(-1 + 2x)(1 + 2x) = 10x

Multiply (-1 + 2x) * (1 + 2x)
(-1(1 + 2x) + 2x * (1 + 2x)) = 10x
((1 * -1 + 2x * -1) + 2x * (1 + 2x)) = 10x
((-1 + -2x) + 2x * (1 + 2x)) = 10x
(-1 + -2x + (1 * 2x + 2x * 2x)) = 10x
(-1 + -2x + (2x + 4x2)) = 10x

Combine like terms: -2x + 2x = 0
(-1 + 0 + 4x2) = 10x
(-1 + 4x2) = 10x

Solving
-1 + 4x2 = 10x

Solving for variable 'x'.

Reorder the terms:
-1 + -10x + 4x2 = 10x + -10x

Combine like terms: 10x + -10x = 0
-1 + -10x + 4x2 = 0

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

Divide each side by '4'.
-0.25 + -2.5x + x2 = 0

Move the constant term to the right:

Add '0.25' to each side of the equation.
-0.25 + -2.5x + 0.25 + x2 = 0 + 0.25

Reorder the terms:
-0.25 + 0.25 + -2.5x + x2 = 0 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.00 + -2.5x + x2 = 0 + 0.25
-2.5x + x2 = 0 + 0.25

Combine like terms: 0 + 0.25 = 0.25
-2.5x + x2 = 0.25

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 = 0.25 + 1.5625

Reorder the terms:
1.5625 + -2.5x + x2 = 0.25 + 1.5625

Combine like terms: 0.25 + 1.5625 = 1.8125
1.5625 + -2.5x + x2 = 1.8125
