## cheriblsm113 2 years ago is -3x^-4y^1 a polynomial

1. poopsiedoodle

Hi, cheriblsm, welcome to OpenStudy. Yes, this is a polynomial. anything with more than one term is a polynomial.

2. cheriblsm113

even if the exponents are negative?

3. poopsiedoodle

yes, the sign doesn't have anything to do with the kind of equation it is. let me know if you need more help. :) by the way, to be more specific, this is also a binomial.

4. cheriblsm113

would you add the exponents as numbers to get the degree?

5. poopsiedoodle

I think the degree is just the highest exponent. Just to make sure, @Hero

6. cheriblsm113

Thank you for your help, my text book does not have any information regarding negative exponents.

7. poopsiedoodle

you're welcome :D

8. poopsiedoodle

wait wat o-o I thought it needed more than one term to be a polynomial.

9. cheriblsm113

so if it has negative exponents it is not a polynomial?

10. poopsiedoodle

OH YEAH, negatives are fractions.

11. cheriblsm113

its a confusing problem.

@cheriblsm113 -3(x^-4) * (y^1) is NOT a polynomial Polynomial terms have variables which are raised to whole-number exponents (or else the terms are just plain numbers); there are no square roots of variables, no fractional powers, and no variables in the denominator of any fractions. Here are some examples shown on the attachment. http://www.purplemath.com/modules/polydefs.htm
