Bhabhanand: Hey!
I need help in question 3 and 4.
In question 3, I got the answer 1/4.
Is it correct?
I need help in question 4 though.
Thanks! :D

chintuchaman23: It should be (2root2-1)/4

chintuchaman23: In 4 apply the identity (a+b)^3=a^3+b^3+3ab(a+b) and then write tge number you get as coefficient of x it would be 3

chintuchaman23: Sorry answer of 4 would be 27

Bhabhanand: Alright.
I have no more doubts.
Thanks a lot for all the help!
