just for practice

If α,β are the roots of the equation ax²+bx+c=0, then calculate , in terms of a,b,c only.

the 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

:P, try second one.

i think in the second one , it should be x→α and not x→∞

then the answer will be 2(b²-4ac)

Yes.. mistake

Adita, you should not make such mistakes in this easy question...
Making mistakes will not help you to acheive AIR-52 in IIT...

which mistake ?

i 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
