To divide these complex numbers you have to multiply by the conjugate of the denominator. That will look like this:
. Multiply straight across the top and straight across the bottom to get
. In the denominator, the 12i and -12i cancel each other out, which is nice. Now, in both the numerator and the denominator we have an i-squared. i-squared is equal to -1, so we will make that substitution in our solution:
. Doing the math on that we have
. We can simplify that as well as write it in standard form:
. Now we will get it into legit standard form, separating the real part of the complex number from the imaginary part.
. That can be reduced to its final answer of
. There you go!
