Simplifying 2(1 + -1k) * x2 + 4kx + k = 0 Reorder the terms for easier multiplication: 2x2(1 + -1k) + 4kx + k = 0 (1 * 2x2 + -1k * 2x2) + 4kx + k = 0 Reorder the terms: (-2kx2 + 2x2) + 4kx + k = 0 (-2kx2 + 2x2) + 4kx + k = 0 Reorder the terms: k + 4kx + -2kx2 + 2x2 = 0 Solving k + 4kx + -2kx2 + 2x2 = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-2x2' to each side of the equation. k + 4kx + -2kx2 + 2x2 + -2x2 = 0 + -2x2 Combine like terms: 2x2 + -2x2 = 0 k + 4kx + -2kx2 + 0 = 0 + -2x2 k + 4kx + -2kx2 = 0 + -2x2 Remove the zero: k + 4kx + -2kx2 = -2x2 Combine like terms: -2x2 + 2x2 = 0 k + 4kx + -2kx2 + 2x2 = 0 The solution to this equation could not be determined.
