wat is a trinomial

an trinomial is an equation with 3 terms such as 2x+3y-6 that's a trinomial.

(a term is the 2x or the 3y or -6.)

To determine if an equation is a trinomial, count the number of terms it has. If there are three terms, then it is a trinomial. Each term in a trinomial can contain variables, constants, and coefficients. In the given example, 2x, 3y, and -6 are the three terms, hence making it a trinomial.
