RD Sharma Solutions are beneficial to students since they assist them in achieving high exam scores. Vedantu's subject matter specialists have developed these solutions, which detail the entire problem-solving process.

From the links below, you can download a free PDF of RD Sharma Solutions for Class 7 Maths Exercise 7.4 of Chapter 7 Algebraic Expressions. The problems in this exercise have been solved by Vedantu specialists, which would make them feel more at ease. The removal of brackets is the subject of this exercise. To simplify algebraic formulas, we start by removing the grouping symbols using the rules below:

  • If a ‘+’ sign precedes a symbol of grouping symbol may be removed without any change in the sign of the terms

  • If a ‘-’ sign precedes a symbol of grouping, the grouping symbol may be removed and the sign of each term is changed.

FAQs on RD Sharma Class 7 Solutions Chapter 7 - Algebraic Expressions (Ex 7.4) Exercise 7.4

1. What does Chapter 7 - Algebraic Expressions (Ex 7.4) Exercise 7.4 Include? What are the topics covered?

There are four exercises in Chapter 7, Algebraic Expressions. The answers to all of the problems in these exercises are included in the RD Sharma Solutions for Class 7 provided here. The following are the topics that will be explored in this chapter:

  • Definition and meaning of algebraic expressions

2. What is the Algebraic Expression of Class 7 of RD Sharma?

Algebraic expressions are made up of letters or alphabets that are used to express numbers without providing their real values. The fundamentals of algebra taught us how to express unknown values using letters like x, y, and z. These letters are referred to as variables in this context. Variables and constants can be combined in an algebraic expression. A coefficient is any value that is placed before and multiplied by a variable.

In mathematics, an algebraic expression is a combination of variables and constants, as well as algebraic operations (addition, subtraction, etc.). Terms are the building blocks of expressions. For example-

4x + 5y – 8,  5x – 11, etc.

These expressions are represented by unknown variables, constants, and coefficients. An expression is defined as the combination of these three terms. In contrast to an algebraic equation, an algebraic expression does not have sides or an equal sign. Some of the examples are:

  • 4x + 3y – 6

  • x – 10

  • 4x2 − 5xy + 5

3. What types of Algebraic expressions are discussed in RD Sharma Class 7 Solutions Chapter 7 - Algebraic Expressions (Ex 7.4) Exercise 7.4 - Free PDF?

Algebraic Expression Types

Algebraic expressions are divided into three categories:

  1. Monomial Expression

  2. Binomial Expression

  3. Polynomial Expression

  • Monomial Expression

An algebraic expression with only one term is called a monomial.

Monomial expressions include the following- 3x4, 3xy, 3x, 8y, etc.

  • Binomial Expression

An algebraic statement with two distinct terms is known as a binomial expression.

Examples of binomial can be- 5xy + 8, xyz + x3, etc.

  • Polynomial Expression

A polynomial is an expression that has more than one term with non-negative integral exponents of a variable.

Polynomial expressions include- ax + by + ca,  x3 + 2x + 3, etc.

4. How can I solve RD Sharma Class 7 Chapter 7 - Algebraic Expressions (Ex 7.4) Exercise 7.4?

The best tool for you to solve Chapter 7- Algebraic expression of Class 7 is RD Sharma Solution PDF. You can get it on the Vedantu website. 

However, To solve any algebraic equation, start by isolating the variable term on one side of the problem, and then using inverse operations to remove any coefficients or exponents as needed. For example, division reverses a coefficient's multiplication, and square roots reverse a second-power exponent's squaring operation.

It's important to remember that if you apply an operation to one side of an equation, you must also apply the identical operation to the opposite side. You can change the way the terms of an equation are expressed without changing their relationship to each other if you follow this rule.
