Simplifying f(x + 9) = x2 + -8x + 6 Reorder the terms: f(9 + x) = x2 + -8x + 6 (9 * f + x * f) = x2 + -8x + 6 (9f + fx) = x2 + -8x + 6 Reorder the terms: 9f + fx = 6 + -8x + x2 Solving 9f + fx = 6 + -8x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -6 + 9f + fx + 8x + -1x2 = 6 + -8x + x2 + -6 + 8x + -1x2 Reorder the terms: -6 + 9f + fx + 8x + -1x2 = 6 + -6 + -8x + 8x + x2 + -1x2 Combine like terms: 6 + -6 = 0 -6 + 9f + fx + 8x + -1x2 = 0 + -8x + 8x + x2 + -1x2 -6 + 9f + fx + 8x + -1x2 = -8x + 8x + x2 + -1x2 Combine like terms: -8x + 8x = 0 -6 + 9f + fx + 8x + -1x2 = 0 + x2 + -1x2 -6 + 9f + fx + 8x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -6 + 9f + fx + 8x + -1x2 = 0 The solution to this equation could not be determined.
