WitrynaComplex Conjugate Root Theorem. 展豪張 contributed. Complex Conjugate Root Theorem states that for a real coefficient polynomial P (x) P (x), if a+bi a+bi (where i i is the imaginary unit) is a root of P (x) P (x), then so is a-bi a−bi. To prove this, we need some lemma first. WitrynaYou ask a good question and you are right in your thinking. By definition, the Principal root of a number is the same sign as the real number. For example, both -4 and +4 are the square roots of 16. So, to talk about just the principal root of 16 means we discuss the "n"th root of 16 that has the "same sign" as the number in question. Since 16 is …

This is not just a coincidence - there is a theorem that says that this will always be true: Theorem 1: A polynomial of degree nhas exactly nroots. However, some of the roots may be very complicated (some may be complex …

WitrynaThis is because the root at 𝑥 = 3 is a multiple root with multiplicity three; therefore, the total number of roots, when counted with multiplicity, is four as the theorem states. Notice that this theorem applies to polynomials with real coefficients because real numbers are simply complex numbers with an imaginary part of zero.
