 # What is the special product rule for binomials?

## What is the special product rule for binomials?

The Difference of Two Squares Another special binomial product is the sum of two numbers times their difference.

## What is the product of squaring a binomial?

The square of a binomial is the sum of: the square of the first terms, twice the product of the two terms, and the square of the last term. I know this sounds confusing, so take a look.. If you can remember this formula, it you will be able to evaluate polynomial squares without having to use the FOIL method.

What is the special product pattern for the square of a binomial?

Comparing the Special Product Patterns

Binomial Squares Product of Conjugates
– Squaring a binomial – Multiplying conjugates
– Product is a trinomial – Product is a binomial
– Inner and outer terms with FOIL are the same. – Inner and outer terms with FOIL are opposites.

What is special product formula?

Lesson Summary Special products are simply special cases of multiplying certain types of binomials together. We have three special products: (a + b)(a + b) (a – b)(a – b)

### What is product of binomial and trinomial?

Another type of polynomial multiplication problem is the product of a binomial and trinomial. Using the distributive property, each term in the binomial must be multiplied by each of the terms in the trinomial.

### What are the three special cases?

The special cases are: trinomials that are perfect squares, a2 + 2ab + b2 and a2 – 2ab + b2, which factor as (a+ b)2 and (a – b)2, respectively; binomials that are the difference of two squares, a2 – b2, which factors as (a + b)(a – b).

What makes a special product?

Special products are simply special cases of multiplying certain types of binomials together. We have three special products: (a + b)(a + b) (a – b)(a – b)

Why is a squaring binomial called a special product?

Let’s start with (a+b)^2. This creates what is called a perfect square trinomial. It is called a special product because there is a specific pattern that squaring a binomial creates. You have 2 choices for simplifying it.

#### How to calculate the square of a binomial?

The square of a binomial is the sum of: the square of the first terms, twice the product of the two terms, and the square of the last term. I know this sounds confusing, so take a look.. If you can remember this formula, it you will be able to evaluate polynomial squares without having to use the FOIL method. It will take practice.

#### Can A trinomial be factored using special products?

If you learn to recognize these kinds of polynomials, you can use the special products patterns to factor them much more quickly. Some trinomials are perfect squares. They result from multiplying a binomial times itself. You can square a binomial by using FOIL, but using the Binomial Squares pattern you saw in a previous chapter saves you a step.

How to find the product of two binomials?

Special products are easier ways to find the product of two binominals than multiplying each term in the first binomial with all terms in the second binomial. Imagine a square with sides of length (a + b). The area of this square is (a + b) (a + b), or (a + b) 2.
