Complex Numbers:

• Complex Numbers Basics: Understand what complex numbers are. They have a real part and an imaginary part, typically written as a + bi, where 'a' is the real part and 'b' is the imaginary part.

• Operations with Complex Numbers: Learn how to add, subtract, multiply, and divide complex numbers. This involves manipulating both the real and imaginary parts.

• Modulus and Argument: Understand the modulus (magnitude) and argument (angle) of a complex number. You should be able to find these values for a given complex number.

• Complex Conjugates: Learn about complex conjugates and how to find them. The complex conjugate of a + bi is a - bi.

• Polar Form: Familiarize yourself with the polar form of complex numbers, which represents them in terms of modulus and argument.

• Quadratic Equations Basics: Know what quadratic equations are and how they are written. They typically have the form $ax^2 + bx + c = 0$.

• Solving Quadratic Equations: Learn how to solve quadratic equations using methods like factoring, completing the square, and the quadratic formula. Practice solving equations of the form $ax^2 + bx + c = 0$.

• Nature of Roots: Understand how to determine the nature of roots (real, complex, equal, or distinct) based on the discriminant $(b^2 - 4ac)$.

• Quadratic Equations and Graphs: Explore the connection between quadratic equations and parabolic graphs. Know how to find the vertex, axis of symmetry, and the direction of the parabola.

• Quadratic Inequalities: Solve quadratic inequalities, where you find the ranges of values for which the quadratic expression is greater than, less than, or equal to zero.

• Word Problems: Practice solving real-world problems that can be modeled using quadratic equations, such as projectile motion, area maximization, and speed-distance-time problems.

### Equations To Score More in Practice Paper of JEE Main Complex Numbers and Quadratic Equations

Equations are the base to solve the JEE Main Practice Paper. You have to know which equation or formula to use while solving the Practice Paper for JEE Main. Find the important equations you need to learn while working out Practice Paper of JEE Main Complex Numbers and Quadratic Equations.

#### Discriminant of a Quadratic Equation:

• $D = b^2 - 4ac$

#### Complex Conjugate:

• $\text{If } z = a + bi, \text{ then } \bar{z} = a - bi$

#### Modulus (Magnitude) of a Complex Number:

• $|z| = \sqrt{a^2 + b^2}$

#### Argument (Angle) of a Complex Number:

• $\theta = \arctan\left(\dfrac{b}{a}\right)$

#### De Moivre's Theorem:

• $z^n = |z|^n \left(\cos(n\theta) + i\sin(n\theta)\right)$
