What are special products in math?
Special products is a Mathematical term in which factors are combined to form products. It is called "special" because they do not need long solutions. The Different types of Special Products 1) Square of a Binomial - this special product results into Perfect Square Trinomial (PST)
What is a special product?
These patterns are called special products. A special product is a product of two binomials that hold a predictable pattern. Before we dive into this topic, let us do a quick recap on the FOIL method and its application towards multiplying binomials. As we have seen before, we can use the FOIL method to multiply binomials.

What is the example of special product?
For example, as x2 + 2x + 1, not 2x + x2 + 1.) If the first and last terms are NOT perfect squares, then the polynomial is not the result of a special product and we can stop looking at other features of the polynomial.

What is a product special?
A Product Specification, commonly referred to as a product spec, is an important product document that outlines key requirements for building a new feature, functionality, or product.
What are three special products?
Recall the three special products:Difference of Squares. x2 - y2 = (x - y) (x + y)Square of Sum. x2 + 2xy + y2 = (x + y)2Square of Difference. x2 - 2xy + y2 = (x - y)2

What is a special factor?
Overview. Some special factoring formulas include the difference of two squares, the sum of two cubes, and the difference of two cubes. If there are three terms or more in the polynomial, students can use strategies such as finding common factors and factoring by grouping.

What does it mean to spec a product?
To write a product specification, you need to have an understanding of what it is. A product spec is a blueprint that outlines the product you will be building, what it is going to look like, and its specific requirements and functions. It may also include the persona or user it is being made for.
What does a product spec look like?
A product specification (also referred to as “product specs”) is a document with a set of requirements that provides product teams the information they need to build out new features or functionality. A good product spec doesn't micro-manage product development.
What are product standards?
Safety standards where goods must comply with rules for the performance, composition, contents, methods of manufacture or processing, design, construction, finish or packaging.
What type of special product is a B 2?
Perfect Squares: The Square of a Sum Given any two numbers a and b, you can expand (a + b)2 or (a - b)2. These are read “a plus b, quantity squared” and “a minus b, quantity squared.”

What is product of sum and difference of two terms?
Product of the Sum and Difference of Two Terms The product of the sum and difference of the same two terms is always the difference of two squares; it is the first term squared minus the second term squared. Thus, this resulting binomial is called a difference of squares.
Square a Binomial Using the Binomial Squares Pattern
Mathematicians like to look for patterns that will make their work easier. A good example of this is squaring binomials. While you can always get the product by writing the binomial twice and using the methods of the last section, there is less work to do if you learn to use a pattern.
Multiply Conjugates Using the Product of Conjugates Pattern
We just saw a pattern for squaring binomials that we can use to make multiplying some binomials easier. Similarly, there is a pattern for another product of binomials. But before we get to it, we need to introduce some vocabulary.
Recognize and Use the Appropriate Special Product Pattern
We just developed special product patterns for Binomial Squares and for the Product of Conjugates. The products look similar, so it is important to recognize when it is appropriate to use each of these patterns and to notice how they differ. Look at the two patterns together and note their similarities and differences.
Key Concepts
In the following exercises, square each binomial using the Binomial Squares Pattern.
Glossary
A conjugate pair is two binomials of the form ; the pair of binomials each have the same first term and the same last term, but one binomial is a sum and the other is a difference.
Square of sum formula
The way to read this special product is: Square of the first, plus double of the first by the second, plus the square of the second:
Square of difference formula
This formula is very similar to the square of sum formula, with the difference of the minus sign in the second term.
Difference of squares formula
This formula is very useful for factoring polynomials and simplifying algebraic fractions when we have the subtraction of two squared terms:
