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