: List all the possible rational zeros of each function
14) f(x)= 3x^4+15
p=(+or-)1: (+or-)15: (+or-)3: (+or-)5:
q= (+or-) 3 "
if q isn't right then, how would you know what is q? This question is from textbook algebra2

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 15 (the last coefficient):

Now let's list the factors of 3 (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 distinct rational zeros of the function that could occur
