Ex: Dividing Complex Numbers

This video provides an example on how to simplify a quotient involving an imaginary number and an example involving a complex number.

I love how the example problems always work out the have easy whole numbers. Wish my math teacher knew how to do that

For the first example; 6-7i
____
3
Why did you only substitute for the only I^2. Was it because i was equal to the  negative square root of one, while i^2 was equal to negative one.

One more question, for the second example why did you multiply both the numerator and the denominator. Why did you not just multiply by i?

[junitandra]

You said to multiply the conjugate of the denominator, shouldn't the first question be multiplied by -3i/-3i?

Hi, just curious about what program(s) you used to write those mathematics and record it. Thanks

[varunselvam]

I meant i^2, the computer automatically corrected it for me.
