- 3. Yea we have to multiply these 2 binomials together but we don't know how.
- 1. hey johnny, emily what's up?
- 2. Well, we're having a problem.
- 4. dont worry I can help you!
- when multiplying binomials we have to use a process called FOIL, FOIL stands for first, outside, inside, last.
- the best way of understanding this is with an example. here we have (2x + 5) (7 +3). we are first going to multiply the first digits in each parenthesis which would be 2x and 7. that gives us 14x. then we do the outside digits which would be the ones in the ends of the parenthesis's, those digits would be 2x and 3, that would be 6x.
- Then we take the digits that are inside the parenthesis those would be 5 and 7 which gives us 35. and Finally we finish multiplying foil when we do the last digits in each parenthesis which would be 15.
- Now that we have our FOIL results we see if we can add them together in this case we can! So from 14x + 6x + 35 + 15 we go to 20x + 50. And that's our answer.
- We get it now thanks, Lily!
