Example 1: Not A Polynomial Due To A Square Root In One Term Consider the expression: 2x + x - 5 This is not a polynomial, since we have a square root in the second term. A polynomial has one root that equals 4+17i. Think about the definition of prime number. How can a fact that the assumed numbers are reducible, proves that root 2 is irrational. Does this make sense? The reason is that all of the exponents are whole numbers for the variable x (2 in the first term, 1 in the second term, and 0 in the third term). They are also the first 3 decimal places in pi. You can learn how to find the domain and range of a polynomial here. This is a polynomial, since the powers of each variable are nonnegative integers.
