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 -3 (the last coefficient):
Now let's list the factors of 1 (the first coefficient):
Now let's divide each factor of the last coefficient by each factor of the first coefficient
Now simplify
These are all the possible rational zeros of the function
