It says that every polynomial with real or complex coefficients has a complex root.

A case that involves complex roots can be solved with the aid of Euler's formula.

Equations with complex roots can be handled in the same way.

Calculating complex roots would require using a different trigonometric form.

This relation applied to polynomials with complex roots is known as Bernstein's inequality.

The complex roots can be shown to be located on or close to the unit circle.

Gently, I lifted them by their complex roots, which knit and curl like a web of intestines.

The spins therefore take values in the form of complex roots of unity.

This article is concerned with finding scalar, real or complex roots, approximated as floating point numbers.

It will pay particular attention to the steamier, not to say sleazier, side of a phenomenon that had complex intellectual roots.
