We have provided a few important points that are covered in NCERT Class 11 Maths Chapter 5 Complex Numbers and Quadratic Equations to help students in their exam preparations. Refer to the points below:

- √-1 is an imaginary quantity and is denoted by i.
- i
^{2}= −1, i^{3}= −i, i^{4}= 1 and, i^{±n}= i^{±k}, n ∈ N where k is the remainder when n is divided by 4. - For any positive real number a, √−a = i√a.
- If a, b are real numbers, then a number z = a + ib is called a complex number.
- Real number a is known as the real part of z and b is known as its imaginary part. We write a = Re(z), b = lm(z).
- A complex number z is purely real if lm(z) = 0 and z is purely imaginary if Re(z) = 0.
- For any two complex numbers, z
_{1}= a_{1}+ ib_{1}and z_{2}= a_{2}+ ib_{2}.- Addition: z
_{1}+ z_{2}= (a_{1}+ a_{2}) + i(b_{1}+ b_{2}) - Subtraction: z
_{1}− z_{2}= (a_{1}− a_{2}) + i(b_{1}− b_{2}) - Multiplication: z
_{1}z_{2}= (a_{1}a_{2}− b_{1}b_{2}) + i(a_{1}b_{2}+ a_{2}b_{1})

- Addition: z
