Binomial Theorem Class 11 Notes
Binomial Theorem Class 11 Notes – Chapter 8 The binomial expression is an expression comprising of two terms connected by -ve or +ve sign. Equations like x + a, 2x -3y, 1x−1×3, 7x−24×3 are examples of binomial expressions. The binomial expansion of (p+q)n will have a total of (n + 1) terms. The coefficients in the binomial expansion follow a …
