Simplifying f(x + 2) = x2 + 3x + 8 Reorder the terms: f(2 + x) = x2 + 3x + 8 (2 * f + x * f) = x2 + 3x + 8 (2f + fx) = x2 + 3x + 8 Reorder the terms: 2f + fx = 8 + 3x + x2 Solving 2f + fx = 8 + 3x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -8 + 2f + fx + -3x + -1x2 = 8 + 3x + x2 + -8 + -3x + -1x2 Reorder the terms: -8 + 2f + fx + -3x + -1x2 = 8 + -8 + 3x + -3x + x2 + -1x2 Combine like terms: 8 + -8 = 0 -8 + 2f + fx + -3x + -1x2 = 0 + 3x + -3x + x2 + -1x2 -8 + 2f + fx + -3x + -1x2 = 3x + -3x + x2 + -1x2 Combine like terms: 3x + -3x = 0 -8 + 2f + fx + -3x + -1x2 = 0 + x2 + -1x2 -8 + 2f + fx + -3x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -8 + 2f + fx + -3x + -1x2 = 0 The solution to this equation could not be determined.
