Simplifying f(x) = x2 + 5x + -2(2f(2)) Multiply f * x fx = x2 + 5x + -2(2f(2)) Reorder the terms for easier multiplication: fx = x2 + 5x + -2(2 * 2f) Multiply 2 * 2 fx = x2 + 5x + -2(4f) Remove parenthesis around (4f) fx = x2 + 5x + -2 * 4f Multiply -2 * 4 fx = x2 + 5x + -8f Reorder the terms: fx = -8f + 5x + x2 Solving fx = -8f + 5x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '8f' to each side of the equation. 8f + fx = -8f + 5x + 8f + x2 Reorder the terms: 8f + fx = -8f + 8f + 5x + x2 Combine like terms: -8f + 8f = 0 8f + fx = 0 + 5x + x2 8f + fx = 5x + x2 Reorder the terms: 8f + fx + -5x + -1x2 = 5x + -5x + x2 + -1x2 Combine like terms: 5x + -5x = 0 8f + fx + -5x + -1x2 = 0 + x2 + -1x2 8f + fx + -5x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 8f + fx + -5x + -1x2 = 0 The solution to this equation could not be determined.
