Maths CBSE 10 CLASS: A Comprehensive Guide to Polynomials, Quadratic Equations, Pair of Linear Equations, Triangles, and Real Numbers
Welcome to this comprehensive guide for the Maths CBSE 10 class! In this article, we will explore the important subtopics of polynomials, quadratic equations, pair of linear equations, triangles, and real numbers. Let's get started!
Polynomials
Polynomials are mathematical expressions that involve variables raised to powers and multiplied by coefficients. They are essential in algebra and are used to solve problems involving roots, factors, and coefficients. The degree of a polynomial is the highest power of the variable(s) it contains.
Types of Polynomials
There are two main types of polynomials:

Monic Polynomials: These are polynomials where the coefficient of the highest power of the variable(s) is 1.

NonMonic Polynomials: These are polynomials where the coefficient of the highest power of the variable(s) is not 1.
Factoring Polynomials
Factoring polynomials involves breaking them down into simpler polynomials by finding the common factors between the terms. This process can be helpful in solving problems and understanding the structure of the polynomial.
Quadratic Equations
Quadratic equations are polynomial equations of the second degree, meaning they have a variable raised to the power of 2. These equations can be solved using various methods, such as factoring, completing the square, or using the quadratic formula.
Solving Quadratic Equations
There are three main methods to solve quadratic equations:

Factoring: Factoring involves finding the factors of the quadratic equation and then setting each factor equal to zero to find the solutions.

Completing the Square: This method involves adding and subtracting a constant value to the quadratic expression to make it a perfect square trinomial, which can then be taken to the next step.

Quadratic Formula: The quadratic formula can be used to solve any quadratic equation in the form axÂ² + bx + c = 0, where a, b, and c are constants.
Pair of Linear Equations
A pair of linear equations is a system of two linear equations with two variables, which can be solved using various methods, such as substitution, elimination, or matrix methods. The solutions to a pair of linear equations are called the intersection points of the lines represented by the equations.
Solving Pair of Linear Equations
There are three main methods to solve a pair of linear equations:

Substitution: This method involves solving one of the equations for one variable and then substituting the expression for that variable into the other equation.

Elimination: This method involves adding or subtracting the two equations to eliminate one of the variables.

Matrix Methods: These methods involve using matrices to represent the system of equations and then finding the inverse of the matrix to solve for the variables.
Triangles
Triangles are geometric figures with three sides and three angles. They are a fundamental concept in geometry and have various applications in real life, such as in architecture and engineering.
Properties of Triangles
There are several properties of triangles, including the sum of the interior angles (180Â°) and the Pythagorean theorem (aÂ² + bÂ² = cÂ², where a and b are the lengths of the legs of a rightangled triangle, and c is the length of the hypotenuse).
Real Numbers
Real numbers are a set of numbers that include integers, rational numbers, and irrational numbers. They are used in various mathematical applications and are essential in understanding the properties and behavior of numbers.
Types of Real Numbers
There are three main types of real numbers:

Integers: These are whole numbers, both positive and negative.

Rational Numbers: These are numbers that can be expressed as the ratio of two integers, such as 3/4 or 5.

Irrational Numbers: These are numbers that cannot be expressed as the ratio of two integers, such as âˆš2 or Ï€.
In conclusion, the Maths CBSE 10 class covers a wide range of topics, including polynomials, quadratic equations, pair of linear equations, triangles, and real numbers. Understanding these subtopics is essential for success in mathematics and can be applied in various reallife situations.
