You can put this solution on YOUR website! recall:
A polynomial function is a function that involves only  integer  or only  integer  of a variable in an equation like the quadratic equation, cubic equation, etc. For example,  is a polynomial. As a general rule of thumb if an algebraic expression has a radical in it then it isn't a polynomial.
A zero polynomial is the one where all the coefficients are equal to  . So, the degree of the zero polynomial is either  , or it is set equal to  .
A polynomial function is made up of terms called monomials.
A monomial is an expression that contains only one term. In other words, a monomial is a polynomial with a single term. Generally, monomials include numbers, variables, or a number and a variable multiplied together, two or more variables multiplied together. A monomial is an expression that does not contain any arithmetic operators.
