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