Unformatted text preview: f , then p must divide a and q must divide a n . Example: List the rational zeros of f ( x ) = x 3 + x 24 x4. Complex Zeros: Consider f ( x ) = x 2 + 4. What are the zeros of f ? If a + bi , where b 6 = 0 , is a zero of a polynomial function f , then . . . is also a zero of the function. Remark: A polynomial function with real coecients of odd degree has at least one real zero. Examples: 1. Given that 1 3 i is a zero of h ( x ) = 3 x 34 x 2 + 8 x + 8, nd the remaining zeros. 2. Find a polynomial function f with integer coecients that has the zeros 2, 1, 3 + 2 i and whose graph passes through (0, 44)....
