Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.If it is satisfied by all numbers in (0,3] then this must be an identity so:
1. If p is an integer {2p-1}=0
2. From x^3 wala term p=+-2 or +-3
3. From x term p=4,2 or 3
4. From [(p/2-1)] term, [p/2]=1 or p belongs to [2,4)
From all this info p=2 or 3 are the only once that satisfy giving the sum 2+3=5
why did we make all coeff 0 can you explain again
Because its an identity. A cubic can have maximum 3 roots, right? But here, there are infinite roots, which means it must be a zero function.
So we equate everything to zero
is that sameer bansal
