Solution for 0=2x+x^2 equation:


Simplifying
0 = 2x + x2

Solving
0 = 2x + x2

Solving for variable 'x'.
Remove the zero:
-2x + -1x2 = 2x + x2 + -2x + -1x2

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

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

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

Factor out the Greatest Common Factor (GCF), '-1x'.
-1x(2 + x) = 0

Ignore the factor -1.

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 '(2 + x)' equal to zero and attempt to solve: Simplifying 2 + x = 0 Solving 2 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + x = 0 + -2 x = 0 + -2 Combine like terms: 0 + -2 = -2 x = -2 Simplifying x = -2

Solution

x = {0, -2}
