Term
How do you find out if a possible zero is actually a rational zero? ------- |

Term
How do you find all the roots for the function f(x)=0? ------------ |
|
Definition
1.) Factor out (x(Opposite Sign of rational zero)rational zero) [This is easily done by using synthetic division with the rational zero] ------------- 2.)Now use the quadratic formula to find the roots of f(x)=0. [Unless it still hasn't formed a quadratic function meaning you must test another rational zero using synthetic division, except you now apply it to the new function, then using quadratic formula find the roots of f(x)=0.] --------------- 3.)Your solution set: (rational zeroes, the roots of (fx)=0) --------- |
