The formulas associated with complex numbers and quadratic equations in Class 11 are essential for understanding the topics well. Here are some of the key formulas you'll encounter:

Complex Numbers:

1. Standard Form: $�+��$ where $�$ and $�$ are real numbers, and $�$ is the imaginary unit with ${�}^2=-1$.
2. Modulus of a Complex Number: $\mathrm{\mid }�+��\mathrm{\mid }=\sqrt{{�}^2+{�}^2}$
3. Conjugate of a Complex Number: The conjugate of $�+��$ is $�-��$.
4. Multiplication of Complex Numbers: $(�+��)(�+��)=��+���+���-��=(��-��)+(��+��)�$
5. Division of Complex Numbers: $\frac{�+��}{�+��}=\frac{(�+��)(�-��)}{(�+��)(�-��)}$

Quadratic Equations:

1. Standard Form of a Quadratic Equation: $�{�}^2+��+�=0$
2. Quadratic Formula: $�=\frac{-�\pm \sqrt{{�}^2-4��}}{2�}$
