Any rational zero can be found through this equation

where p and q are the factors of the last and first coefficients


So let's list the factors of 5



Now let's list the factors of 4



Now let's divide each factor of the last coefficient by each factor of the first coefficient




Now simplify

These are all the possible zeros of the function
