= Trinomial expansion
{wiki=Trinomial_expansion}
Trinomial expansion refers to the process of expanding expressions that are raised to a power and involve three terms, typically represented in the form \\((a + b + c)^n\\), where \\(a\\), \\(b\\), and \\(c\\) are the terms and \\(n\\) is a non-negative integer. The formula for expanding a trinomial can be derived from the multinomial theorem, which generalizes the binomial theorem (the latter which deals only with two terms).
