The expression 9x^2y^3-2x^3z can be best described as which of the following trinomial nomomial binomial not a polynomial
i would say a not poly
Do you have a definition?
how many terms does it have?
What do you have up there that violates the definition of "polynomial"?
Do you ever ride a BIcycle? How many wheels does it have? Make a wild guess...what is a 2 term polynomial called?
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
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
