Simplifying f(x + 3) = 2x2 + 5x + 2 Reorder the terms: f(3 + x) = 2x2 + 5x + 2 (3 * f + x * f) = 2x2 + 5x + 2 (3f + fx) = 2x2 + 5x + 2 Reorder the terms: 3f + fx = 2 + 5x + 2x2 Solving 3f + fx = 2 + 5x + 2x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -2 + 3f + fx + -5x + -2x2 = 2 + 5x + 2x2 + -2 + -5x + -2x2 Reorder the terms: -2 + 3f + fx + -5x + -2x2 = 2 + -2 + 5x + -5x + 2x2 + -2x2 Combine like terms: 2 + -2 = 0 -2 + 3f + fx + -5x + -2x2 = 0 + 5x + -5x + 2x2 + -2x2 -2 + 3f + fx + -5x + -2x2 = 5x + -5x + 2x2 + -2x2 Combine like terms: 5x + -5x = 0 -2 + 3f + fx + -5x + -2x2 = 0 + 2x2 + -2x2 -2 + 3f + fx + -5x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -2 + 3f + fx + -5x + -2x2 = 0 The solution to this equation could not be determined.
