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


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

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

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

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

Reorder the terms:
4x2 = 2 + x

Solving
4x2 = 2 + x

Solving for variable 'x'.

Reorder the terms:
-2 + -1x + 4x2 = 2 + x + -2 + -1x

Reorder the terms:
-2 + -1x + 4x2 = 2 + -2 + x + -1x

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

Combine like terms: x + -1x = 0

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

Divide each side by '4'.
-0.5 + -0.25x + x2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + -0.25x + 0.5 + x2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + -0.25x + x2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + -0.25x + x2 = 0 + 0.5
-0.25x + x2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
-0.25x + x2 = 0.5

The x term is -0.25x.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25x + 0.015625 + x2 = 0.5 + 0.015625

Reorder the terms:
0.015625 + -0.25x + x2 = 0.5 + 0.015625

Combine like terms: 0.5 + 0.015625 = 0.515625
0.015625 + -0.25x + x2 = 0.515625
