1NISHANT SIR DER ????
If a, b, c are the roots of x3+2x2+3x+3 then
\left( \frac{a}{a+1}\right)^3+\left( \frac{b}{b+1}\right)^3+\left( \frac{c}{c+1}\right)^3 is equal to
(Another good one i got from a student)

11thoda lamba aa ra hai[2]
a+b+c=-2
ab+bc+ca=3
abc=-3
solve further!!!!!!!!!
I just got this method in the bag
but will be pleased to see more[1]

Now using the relations a3+b3+c3=(a+b+c)3-3(a+b)(b+c)(c+a), we can evaluate the entire expression....
If full solution is needed, do nudge me!
But I think this is sufficient, isn't it Nishant Sir?
