• Well, finding polynomials is the reverse of finding factors. In the previous lesson, you were given a polynomial and asked to find its factors and zeros. Example 1: Given the factors ( x - 3) 2 (2x + 5), find the polynomial of lowest degree with real coefficients.let's analyze what we already know. ( x...Find x so that f ( x) = x 2 – 8 x – 9 = 0. f ( x) can be factored, so begin there. Therefore, the zeros of the function f ( x) = x 2 – 8 x – 9 are –1 and 9. This means . f (–1) = 0 and f (9) = 0 . If a polynomial function with integer coefficients has real zeros, then they are either rational or irrational values.

• You need two facts: 1) The Fundamental Theorem of Algebra. All polynomials are of the form: P(x) = m(x-r1)(x-r2)...(x-rn) where m is the leading coefficient, and the ri's are the roots. 2) All complex roots come in conjugate pairs: Since (√2)i is a root, so is -(√2)i. Now we know all four roots, so.
