Answer
Definitions: A polynomial is monomial if it has exactly one term. It is called binomial if it has exactly two non-zero terms. A polynomial is a trinomial if it has exactly three non-zero terms. The polynomial $5x - 4y + 3x$ has exactly three terms, i.e. $5x, -4y$ and $3x.$ Therefore, it is a trinomial.
