Now that we know the basics of imaginary numbers, let's expand our knowledge and learn about another concept that is closely tied to imaginary numbers – complex numbers, a number that is consisted of a real part, and an imaginary part. In this section, we will learn what makes up a complex number, as well as how to plot on a complex plane.

Basic concepts: Evaluating and simplifying radicals, Solving quadratic equations using the quadratic formula, Nature of roots of quadratic equations: The discriminant,

Related concepts: Imaginary zeros of polynomials,
