Every polynomial P(x) of degree n>0 has at least one zero in the complex number system. N Zeros Theorem Every polynomial P(x) of degree n>0 can be expressed as the product of n linear factors. Hence, P(x) has exactly n zeros, not necessarily distinct. The Fundamental Theorem of Algebra
2
Find all zeros. Write the polynomial as the product of linear factors.
4
Find all zeros. Factor the polynomial as the product of linear factors.
6
If a polynomial P(x) has real coefficients, and if a+bi is a zero of P(x), then its complex conjugate a-bi is also a zero of P(x) Complex Conjugate Zeros Theorem Find all remaining zeros given the information provided. Degree: 5, 2-4i and 3 and 7i are zeros 2+4i and -7i are also zeros
7
Given a zero of the polynomial, determine all other zeros and write the polynomial as the product of linear factors Conjugates
