WebThis is because over the complex numbers a third order polynomial factors as $(x-a)(x-b)(x-c)$ where $a,b,c$ are the roots. So the constant term, in this case $320 = abc$. So you … WebJun 15, 2024 · The trick now is to find the roots. There is a formula for the roots of degree 3 and 4 polynomials, but it is very complicated. There is no formula for higher degree polynomials. That does not mean that the roots do not exist. There are always \( n\) roots for an \( n^{th}\) degree polynomial. They may be repeated and they may be complex. pool and spa cleaning fort collins co
