Hey, have you noticed something interesting with all our answers?
Look at this last guy in his official complex form:
Each of these answers is a pair -- one with a minusand one with a plus. Like
These are called complex conjugates. For example, the conjugate of
When you are solving quadratic equations, each complex solution will ALWAYS have his conjugate buddy with him!
