Bo, 4.23 is not bigger than 4.3
The roots would be x=-5 and x=-4 but with that website you just do -5 and -4
If I could get more context then that would help. Because an exponent being an odd number doesn’t do anything, so it could be either a negative or a positive
C because if you divide 3/12 you get .25 but 4/18 is .22, which is the better deal
