Let's start by simplifying the given expression using the . Remember, we want our final expression to be in .
Note that there is only one ,
Also, the are nonnegative integers, and there are no variables in denominators. Therefore, the expression is a in one variable. Now, let's identify the leading coefficient and the .
The leading coefficient is the first coefficient when the polynomial is arranged with descending exponents. Here, the leading coefficient of our polynomial is
The degree of a polynomial is the value of the greatest exponent, which in our case is
A degree of
means that it is a quadratic
