The coefficients of ap and aq in the expression of (1 + a)p+q are
(i) Equal
(ii) Equal with opposite signs
(iii) Reciprocals of each other
(iv) None of these
The coefficients of ap and aq in the expression of (1 + a) p+q We know, bp+1 = p+qCp × p and bq+1 = p+qCq × q Coefficient of ap = p+qCp = [p+q]!/p!q! and Coefficient of aq = p+qCq = [p+q]!/p!q! Therefore, coefficients of ap and aq in the expression of (1 + a)p+q are equal.
