The chapter “Binomial Theorem” in NCERT Class 11 Maths introduces the expansion of algebraic expressions using the binomial formula. It explains the general term, middle term, and properties of binomial coefficients, along with the concept of Pascal’s Triangle. Students learn how to expand expressions of the form (a+b)n(a + b)^n(a+b)n using systematic methods.
Key topics include factorial notation, combinations in expansions, properties of binomial coefficients, and practical applications of the theorem. With step-by-step derivations, solved examples, and exercises, students develop clarity in algebraic problem-solving.
The Binomial Theorem forms the foundation for advanced algebra and is widely applied in higher mathematics, probability, and calculus.
This chapter is highly important for Class 11 exams, JEE and other competitive entrance tests, where questions on expansions and coefficients frequently appear.
