## realmadridCR7 one year ago EASY MEDAL Which statement best demonstrates why the following is a non-example of a polynomial? 33 y squared all over x squared - 62y2xz - 35z2y2 The expression has a variable raised to a negative exponent. The expression has a negative coefficient. The expression has a variable raised to a fraction. The expression has a variable in the denominator of a fraction.

@zeinas.

The expression has a negative coefficient <---- http://en.wikipedia.org/wiki/Polynomial

do you know the answer though

6. charlotte123

I Stated It Already He He

idk where you stated it can you tell me it

8. charlotte123

The expression has a negative coefficient - The Second Choice

9. charlotte123

Oh - And Congrats On Yellow!

@charlotte123 >>The expression has a negative coefficient Negative coefficients ARE allowed in polynomials. Consider P(x) = x^3 - 5x - 1 Some other option is the correct answer @realmadridCR7

@Directrix Got Confused With The Positive Integer Exponents Part - My Bad

12. Directrix

I tried to help here but realized that I don't know what the algebraic expression for the possible polynomial is. Then, the OP ran off when I asked for a clarificiation. http://openstudy.com/users/directrix#/updates/52ad07a7e4b0f72fdcf74c7b

33 y squared all over x squared - 62y2xz - 35z2y2 ----> 33y^2/x^2 - 62y^2xz - 35z^2y^2 The expression has a variable raised to a negative exponent <-- I see no variable raised to a negative exponent In the expression. The expression has a variable raised to a fraction <-- I see no variable raised to a fraction In the expression. If It Is Not The expression has a negative coefficient ---> It Would Be The expression has a variable in the denominator of a fraction.

The coefficients in a polynomial can be fractions - But there are no variables In denominators <---- Seems Like The Last One Is The Answer! @Directrix Thanks For The help!

15. Directrix

I think I'll agree to that. But, I still am unsure what this expression really is when written in symbolic form with no words. 33 y squared all over x squared - 62y2xz - 35z2y2 What do you think it is?

16. charlotte123

I believe It would be: 33y^2/x^2 - 62y^2xz - 35z^2y^2

17. Directrix

@charlotte123

18. charlotte123

Which makes sense - Looking at the options

19. Directrix

Are you saying this: 33y^2/ (x^2 - 62y^2xz - 35z^2y^2)

20. Directrix

It does make sense looking at the options.

21. charlotte123

Yes!
