Question 141123
{{{A[1]x^n+A[2]x^(n-1)+A[3]x^(n-3)}}}...{{{A[n-2]x^2+A[n-1]x+A[n]x^0}}}


The leading term is {{{A[1]x^n}}}
The lead coefficient is {{{A[1]}}}
The degree of the polynomial is {{{n}}}

If the degree of the polynomial is 0, then the polynomial is constant
If the degree is 1, the polynomial is linear
If the degree is 2, the polynomial is quadratic
If the degree is 3, the polynomial is cubic
If the degree is 4, the polynomial is quartic.
