I don't understand this: is \(a + b\) a polynomial? They say that a polynomial is filled with constant coefficients and a single variable, that is, a polynomial is in the form \(f(x) = a + bx + cx^2 \cdots \)

Best ResponseYou've already chosen the best response.1yes, a+b is a polynomial of the form: \[f(a.b)=c_0a+c_1b+c_2a^2+c_3b^2+c_4a^2b+c_5ab^2+...\]

Best ResponseYou've already chosen the best response.0Oh, I get where you are getting. The \(f(x)\) is just a specialized type of polynomial

Best ResponseYou've already chosen the best response.1the variables are pretty much accounted for by adding up the appropriate:(a+b)^n parts, n=0,1,2,3,....

Best ResponseYou've already chosen the best response.1think of a poly as a summation: \[f(x)=\sum_{n=0}^{N}(x)^n\] \[f(x,y)=\sum_{n=0}^{N}(x+y)^n\] \[f(x,y,z)=\sum_{n=0}^{N}(x+y+z)^n\] with something applied for constant coeefs
