In this Class 9 Mathematics topic, students learn to recognise and classify algebraic expressions by their terms, variables, coefficients, and powers. The lesson introduces common forms such as monomials, binomials, trinomials, and polynomials, helping learners distinguish expressions and describe their structure accurately. Presented in the “Common Questions” chapter context, it supports clear understanding of the language and notation used in later algebraic work.
Correct answer: A. Monomial
Explanation: The expression \(5x^2\) has only one term, \(5x^2\), so it is a monomial. An exponent of 2 does not mean that there are two terms; terms are separated by addition or subtraction signs. A binomial has two terms, for example, \(5x^2+3\). Exam tip: count the terms before identifying the type of expression.
