I need some help regarding this question, any help would be greatly appreciated. Thx in advance! the expansion will have 23 terms. what value of n will yield 23 terms? hint : look for a pattern in the symmetry and the number of coefficients in the rows of Pascal's triangle ...
Hello, Solid8Snake! Another approach . . . Find so that the coefficients of the and terms in the expansion of are equal. The coefficients of the 11th and 13th terms are: . We have: . Divide by Divide by . . Therefore: .
