71If α,β are the roots of the equation ax2+bx+c=0, then calculate 
, in terms of a,b,c only.
Suppose p(x) is a polynomial and that p(x) - p'(x) = x^2 + 2x +1. Compute p(5).

262the first one was confusing at the first sight ,
just because i was worried about the value of the constant .
realised later that the answer lies in the question itself :)
Ans :50
262i think in the second one , it should be x→α and not x→∞
then the answer will be 2(b2-4ac)
1Adita, you should not make such mistakes in this easy question...
Making mistakes will not help you to acheive AIR-52 in IIT...
9i think the first sum would be easier if p(x)-p'(x)=x2-2x+1
p(x)=x2+1
p(5)=26
lol... P.S. dont comment on my idiotic nature
