Simplifying Kx2 + (k + 1) * x + -1 = 0 Reorder the terms: x2K + (1 + k) * x + -1 = 0 Reorder the terms for easier multiplication: x2K + x(1 + k) + -1 = 0 x2K + (1 * x + k * x) + -1 = 0 Reorder the terms: x2K + (kx + 1x) + -1 = 0 x2K + (kx + 1x) + -1 = 0 Reorder the terms: -1 + kx + 1x + x2K = 0 Solving -1 + kx + 1x + x2K = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '1' to each side of the equation. -1 + kx + 1x + 1 + x2K = 0 + 1 Reorder the terms: -1 + 1 + kx + 1x + x2K = 0 + 1 Combine like terms: -1 + 1 = 0 0 + kx + 1x + x2K = 0 + 1 kx + 1x + x2K = 0 + 1 Combine like terms: 0 + 1 = 1 kx + 1x + x2K = 1 Add '-1x' to each side of the equation. kx + 1x + -1x + x2K = 1 + -1x Combine like terms: 1x + -1x = 0 kx + 0 + x2K = 1 + -1x kx + x2K = 1 + -1x Add '-1x2K' to each side of the equation. kx + x2K + -1x2K = 1 + -1x + -1x2K Combine like terms: x2K + -1x2K = 0 kx + 0 = 1 + -1x + -1x2K kx = 1 + -1x + -1x2K Divide each side by 'x'. k = x-1 + -1 + -1xK Simplifying k = x-1 + -1 + -1xK Reorder the terms: k = -1 + x-1 + -1xK
