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