e.g. '1 -6 11 -6' = x³-6x²+11x-6
A polynomial root (or zero) is a value of x where the polynomial equals zero: p(x) = 0. Finding roots is fundamental in algebra, engineering, physics, and numerical methods. The Fundamental Theorem of Algebra guarantees that a degree-n polynomial has exactly n roots (counting complex roots and multiplicities).
