WebUsing these, we can rewrite the quadratic as f(x) = ax2 − (a + 1)x + 1. Now, it's obvious that x2f(x) = ax4 + smaller terms, and f(1 − x) will also be only quadratic — so for the LHS to equal 2x − x4, it must be that a = − 1 and f(x) = 1 − x2; all that's left is to compute the left hand side in full and see that it solves the equation.
