Simplifying 0 = (k + -1) * x2 + -3x + 5k Reorder the terms: 0 = (-1 + k) * x2 + -3x + 5k Reorder the terms for easier multiplication: 0 = x2(-1 + k) + -3x + 5k 0 = (-1 * x2 + k * x2) + -3x + 5k Reorder the terms: 0 = (kx2 + -1x2) + -3x + 5k 0 = (kx2 + -1x2) + -3x + 5k Reorder the terms: 0 = 5k + kx2 + -3x + -1x2 Solving 0 = 5k + kx2 + -3x + -1x2 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-5k' to each side of the equation. 0 + -5k = 5k + kx2 + -3x + -5k + -1x2 Remove the zero: -5k = 5k + kx2 + -3x + -5k + -1x2 Reorder the terms: -5k = 5k + -5k + kx2 + -3x + -1x2 Combine like terms: 5k + -5k = 0 -5k = 0 + kx2 + -3x + -1x2 -5k = kx2 + -3x + -1x2 Add '-1kx2' to each side of the equation. -5k + -1kx2 = kx2 + -3x + -1kx2 + -1x2 Reorder the terms: -5k + -1kx2 = kx2 + -1kx2 + -3x + -1x2 Combine like terms: kx2 + -1kx2 = 0 -5k + -1kx2 = 0 + -3x + -1x2 -5k + -1kx2 = -3x + -1x2 Reorder the terms: -5k + -1kx2 + 3x + x2 = -3x + 3x + -1x2 + x2 Combine like terms: -3x + 3x = 0 -5k + -1kx2 + 3x + x2 = 0 + -1x2 + x2 -5k + -1kx2 + 3x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -5k + -1kx2 + 3x + x2 = 0 The solution to this equation could not be determined.
