Simplifying 15 + 2x = x(2 + -1x) 15 + 2x = (2 * x + -1x * x) 15 + 2x = (2x + -1x2) Add '-2x' to each side of the equation. 15 + 2x + -2x = 2x + -2x + -1x2 Combine like terms: 2x + -2x = 0 15 + 0 = 2x + -2x + -1x2 15 = 2x + -2x + -1x2 Combine like terms: 2x + -2x = 0 15 = 0 + -1x2 15 = -1x2 Solving 15 = -1x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'x2' to each side of the equation. 15 + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 15 + x2 = 0 Add '-15' to each side of the equation. 15 + -15 + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + x2 = 0 + -15 x2 = 0 + -15 Combine like terms: 0 + -15 = -15 x2 = -15 Simplifying x2 = -15 Reorder the terms: 15 + x2 = -15 + 15 Combine like terms: -15 + 15 = 0 15 + x2 = 0 The solution to this equation could not be determined.
