Simplifying x + -1(2 + -1x) = x(x + 1) + x x + (2 * -1 + -1x * -1) = x(x + 1) + x x + (-2 + 1x) = x(x + 1) + x Reorder the terms: -2 + x + 1x = x(x + 1) + x Combine like terms: x + 1x = 2x -2 + 2x = x(x + 1) + x Reorder the terms: -2 + 2x = x(1 + x) + x -2 + 2x = (1 * x + x * x) + x -2 + 2x = (1x + x2) + x Reorder the terms: -2 + 2x = 1x + x + x2 Combine like terms: 1x + x = 2x -2 + 2x = 2x + x2 Add '-2x' to each side of the equation. -2 + 2x + -2x = 2x + -2x + x2 Combine like terms: 2x + -2x = 0 -2 + 0 = 2x + -2x + x2 -2 = 2x + -2x + x2 Combine like terms: 2x + -2x = 0 -2 = 0 + x2 -2 = x2 Solving -2 = x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x2' to each side of the equation. -2 + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -2 + -1x2 = 0 Add '2' to each side of the equation. -2 + 2 + -1x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1x2 = 0 + 2 -1x2 = 0 + 2 Combine like terms: 0 + 2 = 2 -1x2 = 2 Divide each side by '-1'. x2 = -2 Simplifying x2 = -2 Reorder the terms: 2 + x2 = -2 + 2 Combine like terms: -2 + 2 = 0 2 + x2 = 0 The solution to this equation could not be determined.
