Simplifying f(x + 3) = 3x2 + 3x + -4 Reorder the terms: f(3 + x) = 3x2 + 3x + -4 (3 * f + x * f) = 3x2 + 3x + -4 (3f + fx) = 3x2 + 3x + -4 Reorder the terms: 3f + fx = -4 + 3x + 3x2 Solving 3f + fx = -4 + 3x + 3x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: 4 + 3f + fx + -3x + -3x2 = -4 + 3x + 3x2 + 4 + -3x + -3x2 Reorder the terms: 4 + 3f + fx + -3x + -3x2 = -4 + 4 + 3x + -3x + 3x2 + -3x2 Combine like terms: -4 + 4 = 0 4 + 3f + fx + -3x + -3x2 = 0 + 3x + -3x + 3x2 + -3x2 4 + 3f + fx + -3x + -3x2 = 3x + -3x + 3x2 + -3x2 Combine like terms: 3x + -3x = 0 4 + 3f + fx + -3x + -3x2 = 0 + 3x2 + -3x2 4 + 3f + fx + -3x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 4 + 3f + fx + -3x + -3x2 = 0 The solution to this equation could not be determined.
