Simplifying f(x) = 2x + x2 + 3(4x) + 17f(7) Multiply f * x fx = 2x + x2 + 3(4x) + 17f(7) Remove parenthesis around (4x) fx = 2x + x2 + 3 * 4x + 17f(7) Multiply 3 * 4 fx = 2x + x2 + 12x + 17f(7) Reorder the terms for easier multiplication: fx = 2x + x2 + 12x + 17 * 7f Multiply 17 * 7 fx = 2x + x2 + 12x + 119f Reorder the terms: fx = 119f + 2x + 12x + x2 Combine like terms: 2x + 12x = 14x fx = 119f + 14x + x2 Solving fx = 119f + 14x + x2 Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Add '-119f' to each side of the equation. -119f + fx = 119f + 14x + -119f + x2 Reorder the terms: -119f + fx = 119f + -119f + 14x + x2 Combine like terms: 119f + -119f = 0 -119f + fx = 0 + 14x + x2 -119f + fx = 14x + x2 Reorder the terms: -119f + fx + -14x + -1x2 = 14x + -14x + x2 + -1x2 Combine like terms: 14x + -14x = 0 -119f + fx + -14x + -1x2 = 0 + x2 + -1x2 -119f + fx + -14x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -119f + fx + -14x + -1x2 = 0 The solution to this equation could not be determined.
