If axn is a zero degree polynomial in x, what can be said about a and n?
Both a and n are zero
(a+n) is zero.
n is non zero
a is non zero
A zero degree polynomial is essentially a constant, i.e. any non-zero real number. So, n has to be zero, and a should not be zero.
If axn is a zero degree polynomial in x, what can be said about a?
If a(x)2+bx+c is a monomial in x , what can be said about a, b and c?
