some.random.cool.kid · Answer

I know I have to distribute and also I can do like terms

nnesha · Answer

some.random.cool.kid · Answer

well this is what I have so far 
54 − 27i) − (39 + 5i)
27{-1} - 5{-1} thats the part I was stuck on and Dont I have to change the sign when canceling or something like that?

some.random.cool.kid · Answer

then 54 minus the 39 and now im stuck.

some.random.cool.kid · Answer

nnesha · Answer

well you didn't distribute the 2nd parentheses

nnesha · Answer

why is it 27{-1} = ?

some.random.cool.kid · Answer

sq to power of 2?

some.random.cool.kid · Answer

-1 x -1 imaginary number

nnesha · Answer

oh well no i = sqrt{-1}
i^2 = -1 
but there isn't any i^2

some.random.cool.kid · Answer

so its not power of two?

well we don't have to apply the  foil   method 
distribute 2nd parenthesizes by  -1
and then combine like terms
