Simplifying x2 + (k + 1) * x + 4 = 0 Reorder the terms: x2 + (1 + k) * x + 4 = 0 Reorder the terms for easier multiplication: x2 + x(1 + k) + 4 = 0 x2 + (1 * x + k * x) + 4 = 0 Reorder the terms: x2 + (kx + 1x) + 4 = 0 x2 + (kx + 1x) + 4 = 0 Reorder the terms: 4 + kx + 1x + x2 = 0 Solving 4 + kx + 1x + x2 = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + kx + 1x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + kx + 1x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + kx + 1x + x2 = 0 + -4 kx + 1x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 kx + 1x + x2 = -4 Add '-1x' to each side of the equation. kx + 1x + -1x + x2 = -4 + -1x Combine like terms: 1x + -1x = 0 kx + 0 + x2 = -4 + -1x kx + x2 = -4 + -1x Add '-1x2' to each side of the equation. kx + x2 + -1x2 = -4 + -1x + -1x2 Combine like terms: x2 + -1x2 = 0 kx + 0 = -4 + -1x + -1x2 kx = -4 + -1x + -1x2 Divide each side by 'x'. k = -4x-1 + -1 + -1x Simplifying k = -4x-1 + -1 + -1x Reorder the terms: k = -1 + -4x-1 + -1x
