Solution:
Given expression is in the expansion of binomial th term is
Now, coefficient of x2, in the expansion of
(given)
…..(1)
similarly, the" coefficient of x3, in the expansion of
From Eqs. (i) and (ii), we get
If the coefficients of x2 and x3 are both zero, in the expansion of the expression in powers of x then the ordered pair
(a, b) is equal to
