3/5 can be un-simplified into a number of different fractions. 3/5, 6/10, 12/20, etc.
The way we figure this out is by multiplying each side of the fraction by an integer. Say 2. So if the fraction is 3/4, times the top and bottom by 2 making it 6/8
The only root is -2. The roots are where the function goes through the x-axis. This polynomial goes through in lots of places, but the only answer that matches is -2
