It is a $\"highlight%28cubic%29\"$ $\"highlight%28trinomial%29\"$ .
\n" ); document.write( "It has 3 terms (2x, 10x^2, and -x^3), so it is a trinomial. (The \"tri\" part means 3, as in tricycle).
\n" ); document.write( "The greatest exponent is 3 (in -x^3), so it is a polynomial of degree 3, also called a cubic polynomial.
\n" ); document.write( "(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). \n" ); document.write( "
