Let's start constructing numbers that have both a real and imaginary part. We'll call them complex. We can even plot them on the complex plane and use them to find the roots of ANY quadratic equation. The fun must not stop!
Plot complex numbers on the complex plane.
Adding Complex Numbers
Subtracting Complex Numbers
Multiplying Complex Numbers
Dividing Complex Numbers
Find the absolute value of a complex number.
Complex Roots from the Quadratic Formula
21-26, mostly imaginary and complex numbers
