Unformatted text preview: a 1 , a 2 , , a n , are typically assumed to be real numbers, though some theorems will require integers or rational numbers. a n , the leading coefficient , must be nonzero , although any of the other coefficients could be zero (i.e., their corresponding terms could be missing). a n x n is the leading term . a is the constant term . It can be thought of as a x , where x = 1 . Because n is a nonnegative integer, all of the exponents on x indicated above must be nonnegative integers, as well. Each exponent is the degree of its corresponding term....
