Multiply the top and bottom by "i" That is the factor i/i.

wouldnt it be a negative i?

Why do you think you would need negative "i" ?

OpenStudy (anonymous):

because wouldnt you use the discriminant to remove the i?

There is no discriminant here, at least in the problem as stated. Just try to do that multiplication of top and bottom and see what you get. btw, the support for utilizing the technique I suggested is that any number, complex or not, over the same number is the factor "1" and that is the multiplicative identity so you can legitimately perform that operation.

okay ill give it a try to that would give me 3i/-1

oh wait that would get 3i/-4

$\frac{ 3 }{ 4i } \times \frac{ i }{ i } = \frac{ 3i }{ 4(i ^{2}) } = \frac{ 3i }{ (4)(-1) } = \frac{ -3i }{ 4 }$
