Solution for 1=2(x*x+x-1)-(x-2)*(2x+3) equation: 


Simplifying
1 = 2(x * x + x + -1) + -1(x + -2)(2x + 3)

Multiply x * x
1 = 2(x2 + x + -1) + -1(x + -2)(2x + 3)

Reorder the terms:
1 = 2(-1 + x + x2) + -1(x + -2)(2x + 3)
1 = (-1 * 2 + x * 2 + x2 * 2) + -1(x + -2)(2x + 3)
1 = (-2 + 2x + 2x2) + -1(x + -2)(2x + 3)

Reorder the terms:
1 = -2 + 2x + 2x2 + -1(-2 + x)(2x + 3)

Reorder the terms:
1 = -2 + 2x + 2x2 + -1(-2 + x)(3 + 2x)

Multiply (-2 + x) * (3 + 2x)
1 = -2 + 2x + 2x2 + -1(-2(3 + 2x) + x(3 + 2x))
1 = -2 + 2x + 2x2 + -1((3 * -2 + 2x * -2) + x(3 + 2x))
1 = -2 + 2x + 2x2 + -1((-6 + -4x) + x(3 + 2x))
1 = -2 + 2x + 2x2 + -1(-6 + -4x + (3 * x + 2x * x))
1 = -2 + 2x + 2x2 + -1(-6 + -4x + (3x + 2x2))

Combine like terms: -4x + 3x = -1x
1 = -2 + 2x + 2x2 + -1(-6 + -1x + 2x2)
1 = -2 + 2x + 2x2 + (-6 * -1 + -1x * -1 + 2x2 * -1)
1 = -2 + 2x + 2x2 + (6 + 1x + -2x2)

Reorder the terms:
1 = -2 + 6 + 2x + 1x + 2x2 + -2x2

Combine like terms: -2 + 6 = 4
1 = 4 + 2x + 1x + 2x2 + -2x2

Combine like terms: 2x + 1x = 3x
1 = 4 + 3x + 2x2 + -2x2

Combine like terms: 2x2 + -2x2 = 0
1 = 4 + 3x + 0
1 = 4 + 3x

Solving
1 = 4 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.
