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