Simplifying x2 + -1kx + 4x + k = 0 Reorder the terms: k + -1kx + 4x + x2 = 0 Solving k + -1kx + 4x + x2 = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-4x' to each side of the equation. k + -1kx + 4x + -4x + x2 = 0 + -4x Combine like terms: 4x + -4x = 0 k + -1kx + 0 + x2 = 0 + -4x k + -1kx + x2 = 0 + -4x Remove the zero: k + -1kx + x2 = -4x Add '-1x2' to each side of the equation. k + -1kx + x2 + -1x2 = -4x + -1x2 Combine like terms: x2 + -1x2 = 0 k + -1kx + 0 = -4x + -1x2 k + -1kx = -4x + -1x2 Reorder the terms: k + -1kx + 4x + x2 = -4x + 4x + -1x2 + x2 Combine like terms: -4x + 4x = 0 k + -1kx + 4x + x2 = 0 + -1x2 + x2 k + -1kx + 4x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 k + -1kx + 4x + x2 = 0 The solution to this equation could not be determined.
