Incredible Binomial Expansion Questions 2022
Incredible Binomial Expansion Questions 2022. Let t n denote the number of triangles which can be formed using the vertices of a regular polygon of n sides. Given that the binomial expansion of (l +1.) n is 1 — 6x+30x2 + , of values of x for which this expansion is valid.
The coefficients of the fourth ad thirteenth terms in the binomial expansion of (a + b) n are n c 3 and n c 12 respectively. Coefficient of 4 th term in (a+b) n = coefficient of 13 th term in (a + b) n. Hence find the coefficient of in the expansion.
X2N + 1 ( 2N + 1) = X + X3 6 + 3X5 40 + ⋯.
If n is an integer, b and c also will be integers, and b + c = n. In the binomial expansion of (a + b) n, the coefficients of the 4 th and 13 th terms are equal to each other, find n. (ii) state the set of values of x for which this expansion is valid.
