Complex conjugate

In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, (if and are real, then) the complex conjugate of is equal to The complex conjugate of is often denoted as or . In polar form, the conjugate of is This can be shown using Euler's formula. The product of a complex number and its conjugate is a real number: (or in polar coordinates). If a root of a univariate polynomial with real coefficients is complex, then its complex conjugate is also a root. (Wikipedia).

Factoring polynomials into linear quadratic factors | Linear Algebra MATH1141 | N J Wildberger

Following on from the (necessarily approximate) Fundamental theorem of Algebra, we investigate real polynomials and their (necessarily approximate) factorization into linear and quadratic factors. To clarify this we look more carefully at cyclotomic factorizations of z^n-1 and the connecti
