Answer:

[tex]\frac{4}{17}-\frac{19}{34}i[/tex]

Step-by-step explanation:

1. Approach

To divide complex numbers, first one must set the problem up as a fraction. The one will multiply the fraction by the complex conjugate. A complex conjugate is a complex number with the imaginary part multiplied by negative one. Since a number over itself equals one, this will ensure that the expression remains true. When one multiplies by the complex conjugate, the difference of squares property complex into play, therefore the denominator simplifies down to a real number (remember one can simplify the powers of (i)). Now all one has to do is divide each element in the complex number in the numerator by the real number in the denominator. If it does not divide evenly, one can just simply the fraction.

2. Solving

Set up as a fraction

[tex]\frac{3-4i}{8+2i}[/tex]

Multiply by the complex conjugate

[tex]\frac{3-4i}{8+2i}*\frac{8-2i}{8-2i}[/tex]

Simplify

[tex]\frac{(3-4i)(8-2i)}{(8+2i)(8-2i)}[/tex]

[tex]\frac{24-6i-32i+8i^{2}}{64-4i^{2}}[/tex]

[tex]\frac{24-6i-32i-8}{64-4(-1)}[/tex]

[tex]\frac{16-38i}{64+4}[/tex]

[tex]\frac{16-38i}{68}[/tex]

[tex]\frac{8-19i}{34}[/tex]
