#### Is there a Trinomial Theorem?

Theorem 1 (The Trinomial Theorem): If , , , and are nonnegative integer such that $n = r_1 + r_2 + r_3$ then the expansion of the trinomial $(x + y + z)^n$ is given by $\displaystyle{(x + y + z)^n = \sum_{r_1 + r_2 + r_3 = n} \binom{n}{r_1, r_2, r_3} x^{r_1} y^{r_2} z^{r_3}}$.

What is Square trinomial?

Trinomial squares are also known as perfect square trinomials, and are the squares of binomial expressions. They factor as (a + b)(a + b) or (a – b)(a – b) where a and b are real numbers. Forms such as (a + b)(a -b) are special products that are also called the difference of squares.
