Class 8 Math - Write a trinomial, which contains x²
Answers
Mathematics NCERT Grade 8, Chapter 9: Algebraic Expressions and Identities - The chapters give an insight into concepts related to algebraic expressions.
Expressions are formed from variables and constants.
Section 9.2 gives details about terms, factors, and coefficients.
Terms like monomials, binomials, trinomials and polynomials are discussed in detail with examples.
Expression that contains only one term is called a monomial.
Expression that contains two terms is called a binomial.
An expression containing three terms is a trinomial.
An expression containing, one or more terms with non-zero coefficient (with variables having non-negative exponents) is called a polynomial. A polynomial may contain any number of terms, one or more than one term.
Emphasis is given to important topics like Addition and subtraction of algebraic expressions. Like and unlike terms are discussed under section 9.4.
Like terms are formed from the same variables and the powers of these variables are the same, too. Coefficients of like terms need not be the same.
The discussion moves further to the next topic-multiplication of algebraic expressions.
There are a number of situations in which we need to multiply algebraic expressions: for example, in finding the area of a rectangle, the sides of which are given as expressions.
This topic contains various sub-parts:
Multiplying a Monomial by a Monomial
Multiplying two monomials
Multiplying three or more monomials
Multiplying a Monomial by a Polynomial
Multiplying a monomial by a binomial
Multiplying a monomial by a trinomial
Multiplying a Polynomial by a Polynomial
Multiplying a binomial by a binomial
Multiplying a binomial by a trinomial
