Polynomial with no real roots
WebMar 29, 2024 · Unless x is between 0 and 1, the first two terms are positive, and so the polynomial is positive. Even if x is between 0 and 1, the first two terms are tiny in … WebEven if you restrict to polynomials with real roots, I doubt you can find a simple formula : I think that if there is a rational formula that works for every polynomial with real roots, it should also apply to all polynomials. Let me explain what I mean precisely.
