Topics for Today:
We expanded our discussion on multiplying binomials today to include some common patterns: squaring sums, squaring differences, and the product of a sum and a difference. For each of these cases, we can always use the distributive property or FOIL methods to expand the product; however, as with many aspects in mathematics, recognizing patterns can save a lot of time.
