4c^2-12c+9 is a trinomial because it is in the form of ax^2 + bx + c. In this case, the trinomial is a perfect square trinomial. 4c^2-12c+9 =(2c-3)(2c-3) =(2c-3)^2

A cubic trinomial is an algebraic expression with three terms, where the highest power of the variable is 3. For example, (x^3 + 2x^2 - 3x) is a cubic trinomial. If the expression you're referring to fits this criteria, then yes, it is a cubic trinomial.

There are 2 terms in a binomial. You can be sure of this because the word "bi" means 2, just the same as the word "tri" (like in the term trinomial) means 3. A binomial is a polynomial which is a sum of 2 terms.
