Introduction: Special Cases
Why learn how to factor special cases?
Some people like to find patterns in the world around them, like a game. There are some polynomials that, when factored, follow a specific pattern.
These include:
Perfect square trinomials of the form:
A difference of squares:
A sum of cubes:
A difference of cubes:
In this lesson you will see you can factor each of these types of polynomials following a specific pattern. You will also learn how to factor polynomials that have negative or fractional exponents.
In this lesson you will learn how to do the following:
- Recognize a polynomial that factors into a special product
- Factor special products
- Factor polynomials with negative or fractional exponents
- Factor by substitution
