二项式定理是初中学习的多项式乘法的继续,它所研究的是一种特殊的多项式——二项式的乘方的展开式。二项式定理既是排列组合的直接应用,又与概率理论中的三大概率分布之一的二项分布有着密切联系。掌握好二项式定理既可对初中学习的多项 The binomial theorem is the continuation of the polynomial multiplication of the junior high school learning. It is concerned with the expansion of a special polynomial, the power of the binomial. The binomial theorem is not only the direct application of permutation and combination, but also closely related to the binomial distribution of one of the three probability distributions in probability theory. Have a good grasp of the binomial theorem can learn a lot of junior high school
