Finding Rational Zeros (Day 1) 3

 Rational Zeros  Where the graph of the function crosses the x- axis 4

 If a function has integer coefficients, then every rational zero is in this form…… division : 5

 List all the possible rational zeros  Test the possible rational zeros using synthetic division  “Factor the polynomial and solve” and/or “Use the quadratic formula” and/or “Continue to test more possible zeros using synthetic division”  Solve 6

 Only find all possible rational zeros 7

8 List all possible rational zeros

9 Use synthetic division to find rational zero Factor and Solve the Polynomial

10 List all possible rational zeros

11 Use synthetic division to find rational zero (Check first candidate -2/3) Factor, then use synthetic division again

12 Factor, then solve using quadratic and zero product property
