Binomial Theorem
Multiplying out a bracket raised to a large power by hand is slow, but the coefficients follow a visible triangle. Chapter 7, Binomial Theorem, of the NCERT Mathematics textbook for Class 11 expands a plus b raised to a positive integer power. You will read the coefficients from Pascal triangle and combinations, write any general or middle term directly, and use the expansion to approximate values and to prove divisibility facts. Worked examples keep the link between algebra and counting clear throughout.
