Simplifying x * x + x * 1 + 2x + 2 * 1 = 0 Multiply x * x x^{2}+ x * 1 + 2x + 2 * 1 = 0 Reorder the terms for easier multiplication: x^{2}+ 1x + 2x + 2 * 1 = 0 Multiply 2 * 1 x^{2}+ 1x + 2x + 2 = 0 Reorder the terms: 2 + 1x + 2x + x^{2}= 0 Combine like terms: 1x + 2x = 3x 2 + 3x + x^{2}= 0 Solving 2 + 3x + x^{2}= 0 Solving for variable 'x'. Factor a trinomial. (2 + x)(1 + x) = 0## Subproblem 1

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## Subproblem 2

Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1## Solution

x = {-2, -1}
