How do we cope with the square roots of negative integers and what are complex numbers? Students can better grasp complex numbers and how to use them to solve issues by reading Chapter 5. Additionally, it will discuss the Argand Plane, the square roots of negative numbers, and venture into the world of quadratic equations. You must have previously studied linear and quadratic equations in one or two variables. You will learn more by learning about complex numbers in the chapter Quadratic Equations and Complex Numbers. You’ll discover how to solve equations that don’t have a real-world answer. So let’s get started and swiftly go over this crucial section of the class 11 math curriculum.

Things under the Chapter

  • Properties of Complex Numbers
  • Addition of Two Complex Numbers
  • Subtraction of Two Complex Numbers
  • Multiplication
  • Argand Plane and Polar Representation

You know right, That sounds like a lot. So You don’t need to worry about anything, Doubtconnect, got your back.
