What's the Grid Method of FOILing?
Note:
Ever played tic-tac-toe? Well this method of multiplying two polynomials together revisits that game! In this tutorial, you'll see a fun alternative to the FOIL method. Learn how to set up a tic-tac-toe grid and use it to find the product of two polynomials!
Background Tutorials
-
Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity.
-
What's a Term?
Polynomials are those expressions that have variables raised to all sorts of powers and multiplied by all types of numbers. When you work with polynomials you need to know a bit of vocabulary, and one of the words you need to feel comfortable with is 'term'. So check out this tutorial, where you'll learn exactly what a 'term' in a polynomial is all about.

-
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.
-
What are Like Terms?
Combining like terms together is a key part of simplifying mathematical expressions, so check out this tutorial to see how you can easily pick out like terms from an expression
-
-
Know and apply the properties of integer exponents to generate equivalent numerical expressions.
-
What's the Product of Powers Rule?
Working with exponents can be lots of fun, as long as you understand how they work. In this tutorial you'll see how exponents add when you multiply the same number raised to different exponents!
-
-
Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.
-
What is a Polynomial?
If you learn about algebra, then you'll see polynomials everywhere! In this tutorial, you'll learn the definition of a polynomial and see some of the common names for certain polynomials.
