**Roots of Polynomials AlgebraLAB**

The Rational Zeros Theorem gives us a list of numbers to try in our synthetic division and that is a lot nicer than simply guessing. If none of the numbers in the list are zeros, then either the polynomial has no real zeros at all, or all of the real zeros are irrational numbers.... form of a polynomial to find the zeros as they relate to multiplicity and complex zeros. Example 2: Given the function fx x x x x () 3 33 71 20=-- +- 43 2 . a) List the possible rational zeros …

SECTION 2.5: FINDING ZEROS OF POLYNOMIAL FUNCTIONS has rational zeros, they must be in the list of ± p q candidates, where: p is a factor of a 0, the constant term, and q is a factor of a n, the leading coefficient. Note: We require a 0 0. If a 0 = 0, try factoring out the GCF first. Example Factor fx()= 4x3 5x2 7x +2 completely, and find all of its real zeros.

- Finding Zeros of polynomials *Rational Roots Theorem *Descartes Rule of Signs *Upper and Lower Bounds . Descartes’ Rule of Signs • Suppose that f(x) is a polynomial with real coefficients arranged in descending powers of x. A variation of signs occurs when 2 successive terms have opposite signs [missing terms with 0 coefficients are ignored] – The number of positive zeros of f is either
