Chapter-6 Operations on Algebraic Expressions

About RS Aggarwal Solutions for Class 8 Maths Chapter-6 Operations on Algebraic Expressions

Operations on algebraic expressions involve manipulating and simplifying expressions using various arithmetic operations. Here is a short description of the key operations on algebraic expressions:

Addition and Subtraction: When adding or subtracting algebraic expressions, you combine like terms. Like terms have the same variables raised to the same powers. For example, in the expression 3x + 2y - 5x + 4y, the like terms are 3x and -5x, as well as 2y and 4y. Adding or subtracting these terms gives you the simplified expression -2x + 6y. For RS Aggarwal's class 8 Maths check out the page and if you need home tuition for class 8 Maths find the right tutors

Multiplication: To multiply algebraic expressions, you use the distributive property. This property states that when multiplying a term or expression by another term or expression, you distribute the multiplication over each term. For example, in the expression 2(x + 3), you multiply 2 by each term inside the parentheses, resulting in 2x + 6.

Division: Dividing algebraic expressions involves simplifying or canceling common factors. For example, in the expression (4x^2 - 8x) / 2x, you can divide each term by 2x, resulting in 2x - 4.

Simplification: Simplifying algebraic expressions involves combining like terms, eliminating parentheses, and applying the rules of arithmetic operations. For example, in the expression 3(x + 2) - 2(x - 4), you simplify by distributing the multiplication and combining like terms to get 3x + 6 - 2x + 8, which further simplifies to x + 14.

These operations allow you to perform calculations, solve equations, and manipulate algebraic expressions to simplify them or transform them into a more convenient form for analysis and problem-solving. Practice exercises involving these operations help strengthen your understanding of algebraic expressions and their manipulation.
