Examples of trinomial in the following topics:
-
- When a trinomial is a perfect square, it can be factored into two equal binomials.
- It is important to be able to recognize such trinomials, so that they can the be factored as a perfect square.
- If you are attempting to to factor a trinomial and realize that it is a perfect square, the factoring becomes much easier to do.
- Since the middle term is twice $4 \cdot x$, this must be a perfect square trinomial, and we can factor it as:
-
- A monomial equations has one term; a binomial has two terms; a trinomial has three terms.
- Multiplying binomials and trinomials is more complicated, and follows the FOIL method.
-
- .$ Usually when we multiply two binomials we obtain a trinomial, but in this case, when we FOIL, the outer and inner terms cancel.
-
- A monomial can be multiplied by a polynomial of any size (note that a polynomial is called a binomial if it has two terms and a trinomial if it has three terms).
