How do you use the distributive property when you multiply polynomials?
The distribution property says that
With more polynomials it gets a bit harder. I'll do it the long way:
We have distributed the second binomial, and we now distribute the first binomial (twice):
With larger polynomials the 'book-keeping' may become a bit tedious, and most trained people take shortcuts.
If you have more than two polynomials, best method is to do them step by step, two at a time:
Last check: 2-term times 2-term = 4 terms
4-terms times 2-term = 8-terms.
In practical examples, you will be able to add like terms (like the numbers,
(there are no like terms in this example)
