Best ResponseYou've already chosen the best response.1so do you guys think thats correct descending order

Best ResponseYou've already chosen the best response.2yes. In theory we could order it according to the "b"s , but the a's have a higher power

Best ResponseYou've already chosen the best response.1ok so its correct. So for B I said the term is polynomial

phi

Best ResponseYou've already chosen the best response.2yes, but they also want the number of terms (things between the + or )

Best ResponseYou've already chosen the best response.1I need help with degree part c

phi

Best ResponseYou've already chosen the best response.2they want "4 term polynomial" the degree is the biggest exponent. easy to find, because we order the terms from biggest exponent to smallest

Best ResponseYou've already chosen the best response.1but doesnt 2 of them have 3 as degree?

Best ResponseYou've already chosen the best response.15a^2b is 3 right? and 7a^3 is also 3

phi

Best ResponseYou've already chosen the best response.2yes, we should count a^2 b as degree 3 but what we care about is the term with the biggest exponent. (in this case 3) it does not matter if there are more than one term with that degree.

phi

Best ResponseYou've already chosen the best response.2no. just 3 if we did not have 7a^3, the degree would still be 3 (because of the 5a^2b) and if we did not have either of those, the degree would be 2 (from 13ab)

Best ResponseYou've already chosen the best response.1so i just write 3 where it says state the degree of the polynomial
