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 are the Special Products of squares?
Special Products involving Squares. The following special products come from multiplying out the brackets. You'll need these often, so it's worth knowing them well. a(x + y) = ax + ay (Distributive Law) (x + y) (x − y) = x 2 − y 2 (Difference of 2 squares) (x + y) 2 = x 2 + 2xy + y 2 (Square of a sum) (x − y) 2 = x 2 − 2xy + y 2 (Square of ...
What is the formula for special product of two numbers?
These special product formulas are as follows: (a + b)(a + b) = a^2 + 2ab + b^2 (a - b)(a - b) = a^2 - 2ab + b^2 (a + b)(a - b) = a^2 - b^2

What is the product of binomial and trinomial?
Answer and Explanation: To multiply a binomial and a trinomial, distribute each term in the binomial to each term in the trinomial. See full answer below.
What are the 6 types of factoring?
The lesson will include the following six types of factoring:Group #1: Greatest Common Factor.Group #2: Grouping.Group #3: Difference in Two Squares.Group #4: Sum or Difference in Two Cubes.Group #5: Trinomials.Group #6: General Trinomials.
What is special product of binomial?
Some special products of binomials suggest other patterns, such as the product of the sum and difference of two expressions, the product of squaring the sum of an expression, and the product of squaring the difference of an expression.
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:
