Unit: Complex Numbers

Lesson Preview

You may recall the general form of the quadratic equation given by:

ax2+bx+c=0ax^2+bx+c=0

where a,b,cRa,b,c \in \mathbb{R}, and a0a\neq 0.

You may also recall that the solutions to any equation of this form are given by the quadratic formula:

x=b±b24ac2a.x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}.

We will not derive this formula
