FAQs on RS Aggarwal Solutions Class 7 Chapter-6 Algebraic Expressions (Ex 6C) Exercise 6.3
1. What are like and unlike terms in Algebraic Expressions?
The like and unlike terms in Algebraic Expressions is explained below:
Terms that are similar and those that are different.
Like terms are those with the same algebraic factors, whereas unlike terms are those with different algebraic factors.
We use the following simple procedures to determine whether the given phrases are similar or dissimilar:
Don't worry about the numerical coefficients. Pay attention to the algebraic aspects of the concepts.
Check to see if the variables in the terms are identical.
Check to see if the powers of each variable in the terms are equal.
It's worth noting that when deciding on similar terms:
(i) The terms' numerical coefficients
(ii) It makes no difference which order the variables are multiplied in the terms.
2. Write a note on Algebraic Expressions
Algebraic terms can be solved using Mathematical operations like addition and subtraction.
When adding or subtracting two or more algebraic equations, like terms from both expressions are combined, while unlike terms are left alone.
A like term having a numerical coefficient equal to the sum of the numerical coefficients of all like terms is called the sum of two or more like terms.
A like word having a numerical coefficient equal to the difference between the numerical coefficients of two like terms is called a difference between two like terms.
2y + 3x 2x + 4y x(32) + y(2+4) x+6y is an Example.
3. What are the types of Algebraic Expressions?
The types of Algebraic Expressions are:
Monomial Expression - A monomial expression is an Algebraic Expression with only one term. For instance, 2x4, 2xy, and so forth.
Binomial Expression - A binomial expression is made up of two terms that are mutually exclusive.
For instance, 2xy + 4, xyz + x2, and so on.
Polynomial Expression - A polynomial expression is one that has more than one term with non-negative integral exponents of a variable. Examples include ab+bc+ca, and so on.
