Answer:

[tex]-\frac34 -\frac14 i[/tex]

Step-by-step explanation:

Let's start with distributing: [tex]\frac1{4i}-\frac{3i}{4i}[/tex] Simplify i with i in the second term, and rearrange.[tex]-\frac34 +\frac1{4i}[/tex]. Since i in the denominator looks ugly, let's multiply top and bottom by i. [tex]-\frac34 +\frac i{4i^2} = -\frac34 +\frac i{4(-1)} =-\frac34 -\frac14 i[/tex]. The middle passage is based on the fact that, by definition, [tex]i^2=-1[/tex]
