- Distribute each term of the binomial to each term of the trinomial.

- In the example (a+b)(c-d+e) you distribute (multiply) 'a' to get 'ac-ad+ae' and then

you distribute '+b' to get 'bc-bd+be'. So the answer to (a+b)(c-d+e)= ac-ad+ae+bc-bd+be.

- In another example (a-b)(c-d+e) you distribute (multiply) 'a' to get 'ac-ad+ae' and then

you distribute '-b' to get '-bc+bd-be'. So the answer to (a-b)(c-d+e)= ac-ad+ae-bc+bd-be.
