Best ResponseYou've already chosen the best response.0oh so the closer x is to the front would be first or last?

Best ResponseYou've already chosen the best response.1Start with the term with the highest exponent of x and then write each term with the next lower exponent of x, and keep going until you have all terms.

Best ResponseYou've already chosen the best response.1The higher the exponent of x is the earlier the term is written.

Best ResponseYou've already chosen the best response.0so the 7x one first right?

Best ResponseYou've already chosen the best response.1Look below. The exponents of x are in red. Notice that for the term \(3xy^5\), there is an exponent of 1 on the x. That is because x is the same as \(x^1\) \(\Large x^\color{red}{4}y^2 + 7x^\color{red}{3}y^3  3x^\color{red}{1}y^5 + 2x^\color{red}{2}y^4\) Now you pout the terms in order starting with the term with exponent 5. Also, keep in mind that a negative sign to the left of a term belongs to that term.

Best ResponseYou've already chosen the best response.17 is a coefficient. A number that is a factor of the term. It is not an exponent.
