Prove the binomial theorem

WebbMore Proofs. 🔗. The explanatory proofs given in the above examples are typically called combinatorial proofs. In general, to give a combinatorial proof for a binomial identity, say A = B you do the following: Find a counting problem you will be able to answer in two ways. Explain why one answer to the counting problem is . A. WebbBinomial Expansion Examples. 1. Expand (a+b) 5 using binomial theorem. Solution: Here, the binomial expression is (a+b) and n=5. So, using binomial theorem we have, 2. Find the middle term of the expansion (a+x) 10. Solution: Since, n=10(even) so the expansion has n+1 = 11 terms. Hence there is only one middle term which is
