x3 + 2V3x - 1 = not a polynomial
6xV2 + 3x - 4 = not a polynomial
How to determine if an expression is a polynomial?
• All the exponents in the algebraic expression must be non-negative integers.
• any variables in the expression must have whole-number powers.
How to determine if a expression is not a polynomial?
• If an algebraic expression has a radical in it then it isn't a polynomial.
• It is not a polynomial if it has a variable under the negative exponents.
