    What is binomial theorem?

    The binomial theorem expands (a + b)ⁿ using binomial coefficients, giving general and middle terms without multiplying out.

    Why it matters

    It is a scoring Class 11 chapter and a standard source of JEE and other entrance questions.

    Key concepts you will practise

    • General term T(r+1) = nCr aⁿ⁻ʳ bʳ
    • Middle term(s) of an expansion
    • Term independent of x
    • Properties of binomial coefficients

    Tips that save marks

    • Count terms from the general term rather than expanding.
    • For "independent of x", set the total power of x to zero and solve for r.

    Frequently asked questions

    How many terms does (a + b)ⁿ have?

    Exactly n + 1 terms.

    What is the middle term when n is odd?

    There are two middle terms — the ((n+1)/2)th and ((n+3)/2)th terms.
