Best ResponseYou've already chosen the best response.0no. you find the number of roots based of the highest exponent. in this equation the highest exponent in 3. thats how many answer or roots you should find.

Best ResponseYou've already chosen the best response.0some roots may be complex or the roots might be all real! we need to check that to see

Best ResponseYou've already chosen the best response.0Sorry, I didn't see the 3 at the end. To find the roots, you can use the quadratic formula

Best ResponseYou've already chosen the best response.0hhmm i don't think there a quadratic formula for a third degree poly in fact, quad mean (2n degree) so even the term does not fit but surely there is a formula for a third degree equations but somewhat complex than the usual quadratic formula for parabolas

Best ResponseYou've already chosen the best response.0what you can actually do here use the descartes rule of sign to see how many possible roots or actually go and work out the solutions using rational theorem
