Best ResponseYou've already chosen the best response.0you can FOIL or use the table like last time. Which option works best for you?

Best ResponseYou've already chosen the best response.0foil the table is a little confusing.

Best ResponseYou've already chosen the best response.0ok what do you get when you FOIL (23i)(3i)

Best ResponseYou've already chosen the best response.0i^2 is 1 so \(\Large 16\color{red}{i^2}\) turns into \(\Large 16\color{red}{(1)}\)

Best ResponseYou've already chosen the best response.0ok great, so 16(1) = 16+1 = 17  \[\large \color{red}{(23i)(3i)}\color{blue}{(4i)(4+i)} =\color{red}{311i}\color{blue}{17} = 1411i\]

Best ResponseYou've already chosen the best response.0are you saying that they wanted you to multiply `(23i)(3i)` and `(4i)(4+i)` ??

anonymous

Best ResponseYou've already chosen the best response.0actually i put those answers both into the website they were both incorrect

Best ResponseYou've already chosen the best response.0hwy was the answer supposed to be 1411i?

jim_thompson5910

Best ResponseYou've already chosen the best response.0because the 3 and 17 combine to 14

Best ResponseYou've already chosen the best response.0(311i)  (17) = 311i  17 = (317) + (11i) = 14  11i

Best ResponseYou've already chosen the best response.0so instead of a negative is a possitive

jim_thompson5910

Best ResponseYou've already chosen the best response.0so after filling the boxes and simplifying the expressions in each box, we end up with dw:1441075014939:dw since \[\Large i^2*\sqrt{4} = 1*2 = 2\]
