Simplifying f(x) = 3x2 + 2x + -1f(4) Multiply f * x fx = 3x2 + 2x + -1f(4) Reorder the terms for easier multiplication: fx = 3x2 + 2x + -1 * 4f Multiply -1 * 4 fx = 3x2 + 2x + -4f Reorder the terms: fx = -4f + 2x + 3x2 Solving fx = -4f + 2x + 3x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '4f' to each side of the equation. 4f + fx = -4f + 2x + 4f + 3x2 Reorder the terms: 4f + fx = -4f + 4f + 2x + 3x2 Combine like terms: -4f + 4f = 0 4f + fx = 0 + 2x + 3x2 4f + fx = 2x + 3x2 Reorder the terms: 4f + fx + -2x + -3x2 = 2x + -2x + 3x2 + -3x2 Combine like terms: 2x + -2x = 0 4f + fx + -2x + -3x2 = 0 + 3x2 + -3x2 4f + fx + -2x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 4f + fx + -2x + -3x2 = 0 The solution to this equation could not be determined.
