Best ResponseYou've already chosen the best response.1My example shows to put the i on the outside of the equation like this (9/2 +1/2) + (3/2  7/2)i Im not sure what to do next

Best ResponseYou've already chosen the best response.2I wouldn't do it like that. Our answer has to be in the form of ai+b or a+bi... the same rule applies for subtraction aib or abi so what I would've done is to combine the like terms as in put all the terms without the i's to the left and all terms with the i's to the right

Best ResponseYou've already chosen the best response.2now the denominators are the same which is good because we don't have to use GCF or LCD ... so can you tell me what 9+3 is? and 17 ?

Best ResponseYou've already chosen the best response.2alright so now we have \[\frac{6}{2}+\frac{6}{2}i\] so what's 6 divided by 2

Best ResponseYou've already chosen the best response.1Im trying to follow but Id like to follow the examples with the i on the outside

Best ResponseYou've already chosen the best response.2you need to rearrange the terms a bit before you can factor the i outside.

Best ResponseYou've already chosen the best response.1I did another problem like this (5+5i) + (9+8i) = (5+5) + (9+8)i 5+9 + 5+8 4 + 13i

Best ResponseYou've already chosen the best response.2there's a problem with that

Best ResponseYou've already chosen the best response.1What would that be?? The answer is correct

Best ResponseYou've already chosen the best response.2(5+5i)+(9+8i) you have to rearrange the terms first it should look something like this 5+9+5i+8i and then it would be 4+13i which is right, but you need to do some rearranging first

Best ResponseYou've already chosen the best response.2either combine like terms or take the i outside 5+9+(5+8)i 4+13i

Best ResponseYou've already chosen the best response.2the same goes with this \[\frac{9}{2}+\frac{3}{2}+\frac{1}{2}i\frac{7}{2}i \] \[\frac{9}{2}+\frac{3}{2}+(\frac{1}{2}\frac{7}{2})i\]

Best ResponseYou've already chosen the best response.1All of my examples do it with the i on the outside so its easier for me to understand

Best ResponseYou've already chosen the best response.2there's more than one method to doing this problem and it all gives the same result as long as you do the correct arithmetic.

Best ResponseYou've already chosen the best response.2let me rewrite the top portion... it's not displaying right

Best ResponseYou've already chosen the best response.2\[\frac{9}{2}+\frac{1}{2}i+\frac{3}{2}\frac{7}{2}i\] \[\frac{9}{2}+\frac{3}{2}+\frac{1}{2}i\frac{7}{2}i \] [rearrange the terms] \[\frac{9}{2}+\frac{3}{2}+(\frac{1}{2}\frac{7}{2})i \] [factor the i so it appears on the outside] \[\frac{6}{2}+(\frac{6}{2})i \] [solve for the numerators] last step is division
