Complex Conjugates - Imaginary and Complex Numbers
How do we divide by a complex number? Can you get one complex and one real solution to a quadratic? The key to answering these questions is complex conjugate pairs. In this video we define a complex conjugate, look at how complex roots work for quadratic equations and REAL-ise the denominator using the 'sum of two squares' result.
Next in the playlist we will be exploring complex and real roots of cubics and quartics, and then after that we will discover the Argand diagram!
