It is a highlight%28cubic%29highlight%28trinomial%29.
It has 3 terms (2x, 10x^2, and -x^3), so it is a trinomial. (The "tri" part means 3, as in tricycle).
The greatest exponent is 3 (in -x^3), so it is a polynomial of degree 3, also called a cubic polynomial.
(The cubic word comes from the fact that a box-shaped object has 3 dimensions that we can measure, and if the 3 measures are all x, the volume would be x^3, also called x cubed).
