Find a polynomial with specified zeros.
For a polynomial function with integer coefficients, find the rational zeros and the other zeros, if possible.
Use Descartes’ rule of signs to find information about the number of real zeros of a polynomial function with real coefficients.
We will now allow the coefficients of a polynomial to be complex numbers. In certain cases, we will restrict the coefficients to be real numbers, rational numbers, or integers, as shown in the following examples.
