ok you could look for all possible rational roots, but you have many to try

Answer 6

fractions were numerator divides 22 and denominator divides 4 so lots of choices

there is no snap way of doing this really. it is a 4th degree polynomial and although there is a formula for it, it would fill an entire page and not be easy to use
