Let P(x) be a polynomial with degree 3, consider the polynomial
Q(x)=(x^{3}2x+1P(x))(2x^{3}5x^{2}+4P(x)).
Assume that Q(x)≤0, ∀x and P(0)=3. Calculate Q(1).

Ah. Of course. Thanks.
I didn't see the 3rd intersection because I was looking at the 2 curves on Desmos and staying near the origin.
I should have also graphed f1  f2
