Simplifying (4k + 1) * x2 + -1(k + 10) * x + 2k = 0 Reorder the terms: (1 + 4k) * x2 + -1(k + 10) * x + 2k = 0 Reorder the terms for easier multiplication: x2(1 + 4k) + -1(k + 10) * x + 2k = 0 (1 * x2 + 4k * x2) + -1(k + 10) * x + 2k = 0 Reorder the terms: (4kx2 + 1x2) + -1(k + 10) * x + 2k = 0 (4kx2 + 1x2) + -1(k + 10) * x + 2k = 0 Reorder the terms: 4kx2 + 1x2 + -1(10 + k) * x + 2k = 0 Reorder the terms for easier multiplication: 4kx2 + 1x2 + -1x(10 + k) + 2k = 0 4kx2 + 1x2 + (10 * -1x + k * -1x) + 2k = 0 Reorder the terms: 4kx2 + 1x2 + (-1kx + -10x) + 2k = 0 4kx2 + 1x2 + (-1kx + -10x) + 2k = 0 Reorder the terms: 2k + -1kx + 4kx2 + -10x + 1x2 = 0 Solving 2k + -1kx + 4kx2 + -10x + 1x2 = 0 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '10x' to each side of the equation. 2k + -1kx + 4kx2 + -10x + 10x + 1x2 = 0 + 10x Combine like terms: -10x + 10x = 0 2k + -1kx + 4kx2 + 0 + 1x2 = 0 + 10x 2k + -1kx + 4kx2 + 1x2 = 0 + 10x Remove the zero: 2k + -1kx + 4kx2 + 1x2 = 10x Add '-1x2' to each side of the equation. 2k + -1kx + 4kx2 + 1x2 + -1x2 = 10x + -1x2 Combine like terms: 1x2 + -1x2 = 0 2k + -1kx + 4kx2 + 0 = 10x + -1x2 2k + -1kx + 4kx2 = 10x + -1x2 Reorder the terms: 2k + -1kx + 4kx2 + -10x + x2 = 10x + -10x + -1x2 + x2 Combine like terms: 10x + -10x = 0 2k + -1kx + 4kx2 + -10x + x2 = 0 + -1x2 + x2 2k + -1kx + 4kx2 + -10x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 2k + -1kx + 4kx2 + -10x + x2 = 0 The solution to this equation could not be determined.
