A polynomial is a combination of terms separated using or signs. Polynomials cannot contain any of the following:
1. Variables raised to a negative or fractional exponent. (,,).
2. Variables in the denominator. (,,).
3. Variables under a radical. (,,).
4. Special features. (trig functions, absolute values, logarithms, ).
Simplify each term.
Rewrite as .
Since both terms are perfect squares, factor using the difference of squares formula, where and .
Determine if the expression breaks any of the rules.
Determine if the expression is a polynomial.
Not a polynomial
