15. Definition: The Roots/Zeroes of polynomials If f(r) = 0 , then r is a zero/root/ solution of the polynomial equation That is, f(x) = (x-r) Q(x). Remarks: 1. The Fundamental Theorem of Algebra states that every polynomial equation has at least one root, which may be a real or a complex number. 2. If f(x) is of degree n, then there will be n linear factors. 3. Every polynomial equation of degree n has exactly n roots. 4. Complex roots always occur in conjugate pairs, a+bi and a-bi. 5. If the coefficients of the equation
