If a binomial expression (x y) n is to be expanded, a binomial expansion formula can be used to express this in terms of the simpler expressions of the form ax by c in which 'b' and 'c' are non negative integers The value of 'a' completely depends on the value of 'n' and 'b'We obtain f (a)=c0 Next, we take derivative on (3) so that f 0(x)= X1 n=1 cnn(x¡a) n¡1=c 1c2¢2(x¡a)c3¢3(x¡a) 2c 4¢4(x¡a) 3 (4) Setting xIt is quite easy if you know Pascal's triangle Pascal's triangle represents coefficients of binomial expansion with inegral index 3rd term will be 15a⁴b², and its coefficient is 15 You can also make use of general term which is represented by T (r1) and given as, T (r1)= nCr a^ (nr)b^r In your case n=6, and for 3rd term put r=2
