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

directrix · Answer

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.

mertsj · Answer

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