Lesson 7-8 Special Products

Three Shortcuts When multiplying binomials, there are three types of problems that always follow specific patterns. Square of a Sum Square of a Difference Product of a Sum and a Difference

Square of a Sum Use FOIL to solve Notice a pattern? Square of a Sum:

Examples Solve Identify a and b. Plug them into the formula.

Square of a Difference Exactly the same as square of a sum, except the middle term will be negative. Square of a Difference:

Product of a Sum and a Difference Solve using FOIL Notice a Pattern? is called the Difference of two Squares

Examples Solve
