If someone could explain as to how I can figuere this out that would be fantastic.

2

pratyush5 · Answer

to find out the the degree of the polynomial just look ate all the powers of the variable .
the highest here is x^2 . therefore degree of the polynoliam is 2

pratyush5 · Answer

polynoliam :P lol polynomial* :P

ate? at* xD

typing error @uri  :P

pratyush5 · Answer

happens sometimes :P lol

uri · Answer

Degree of polynomial is the highest power.. :P which is 3x^2 so 2.

Ahh thanks guys :P

Be careful, because this concerns a polynomial function with two variables. In general the order is the highest order over all variables, so if the example would have been"

xy^2 + 3*x^2 -7 +x

the total order would be 3 because of the summation of the order of x (=1) and the order of y(=2) in the first term. Usually, the question would be more correct if asked for the order w.r.t. one of the variables. In that case, this example would be order 2 for x (because of 3*x^2) and order 2 for y (due to x*y^2).
