Simplifying 0 = x2 + 2kx + 9k + -8 Reorder the terms: 0 = -8 + 9k + 2kx + x2 Solving 0 = -8 + 9k + 2kx + x2 Solving for variable 'k'. Move all terms containing k to the left, all other terms to the right. Add '-9k' to each side of the equation. 0 + -9k = -8 + 9k + 2kx + -9k + x2 Remove the zero: -9k = -8 + 9k + 2kx + -9k + x2 Reorder the terms: -9k = -8 + 9k + -9k + 2kx + x2 Combine like terms: 9k + -9k = 0 -9k = -8 + 0 + 2kx + x2 -9k = -8 + 2kx + x2 Add '-2kx' to each side of the equation. -9k + -2kx = -8 + 2kx + -2kx + x2 Combine like terms: 2kx + -2kx = 0 -9k + -2kx = -8 + 0 + x2 -9k + -2kx = -8 + x2 Reorder the terms: 8 + -9k + -2kx + -1x2 = -8 + x2 + 8 + -1x2 Reorder the terms: 8 + -9k + -2kx + -1x2 = -8 + 8 + x2 + -1x2 Combine like terms: -8 + 8 = 0 8 + -9k + -2kx + -1x2 = 0 + x2 + -1x2 8 + -9k + -2kx + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 8 + -9k + -2kx + -1x2 = 0 The solution to this equation could not be determined.
