Answer

Does not make sense.

Work Step by Step

No, the polynomial doesn't have to be written in standard form, where its first term has the highest degree. It could be given as, for example $3x^{2}-7-x+x^{3}.$ The first term's degree is 2, (the sum of exponents of all the variables in the term). This is not the degree of the polynomial, as it is not the term with the highest degree. The last term has degree 3, and this is in fact the degree of the polynomial.
