Rational Zeros Theorem – Day 1 6-9 Rational Zeros Theorem – Day 1 SWBAT Identify the possible rational zeros of a polynomial. Find all the rational zeroes of a polynomial. Holt McDougal Algebra 2 Holt Algebra 2

Definitions Rational Zeros Theorem: tells us how to make a list of all potential rational zeros for a polynomial function with integer coefficients. The first coefficient is ‘q’ the last (constant) is ‘p’. Find factors of both to create

Ex 1: Find the rational zeros of: f(x) = 3x3 + 4x2 – 5x – 2 p = -2 q = 3

Ex 2: Given: a) List all the possible rational zeroes of each functions. b) Which ones work using the remainder theorem?
