## NatalieLove 2 years ago The expression 9x^2y^3-2x^3z can be best described as which of the following trinomial nomomial binomial not a polynomial

1. NatalieLove

i would say a not poly

2. tkhunny

Do you have a definition?

3. NatalieLove
4. Mertsj

how many terms does it have?

5. tkhunny

What do you have up there that violates the definition of "polynomial"?

6. NatalieLove

2

7. Mertsj

Do you ever ride a BIcycle? How many wheels does it have? Make a wild guess...what is a 2 term polynomial called?

8. tkhunny

Of course, we should agree that it IS a polynomial, first.

Our friend Paul writes with clarity about polynomials at the link: http://tutorial.math.lamar.edu/Classes/Alg/Polynomials.aspx Two blurbs from his notes are attached below. It is possible to have a polynomial with three variables as does the polynomial: 9x² y^³ - 2x³ z

10. Directrix

You are asking about the number of terms in the polynomial P(x) = 9x² y^³ - 2x³ z To help you with that, study the attached chart.

It's not rocket science...it's a binomial
