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


Simplifying
x2 = x + -2(x + 2 + x + -2)

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

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

Combine like terms: x + x = 2x
x2 = x + -2(2x)

Remove parenthesis around (2x)
x2 = x + -2 * 2x

Multiply -2 * 2
x2 = x + -4x

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

Solving
x2 = -3x

Solving for variable 'x'.

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

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

Factor out the Greatest Common Factor (GCF), 'x'.
x(3 + x) = 0

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(3 + x)' equal to zero and attempt to solve: Simplifying 3 + x = 0 Solving 3 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + x = 0 + -3 x = 0 + -3 Combine like terms: 0 + -3 = -3 x = -3 Simplifying x = -3

Solution

x = {0, -3}
