xyz y is the quotient for both the divisors the same ?
P(x) be a polynomial of degree at the most 5 which leaves the reaminders -1 and 1 upon division by (x-1)3 and (x+1)3
1)....find the no of real roots of p(X)=0
2)....the max value of y=P''(x) can be obtained at x
3).....the sum of pairwise product of all roots(real and complex) of P(x)=0

P(x)=a1x5+a2x4+....+a5
P(1)=p(ω)=p(ω2)=1
-3=3a5+3a3
similarly u know dat P(-1)=P(-w)=P(-w2)=1
use this to find the coefficients.
kaustab,,,why are u posting last year's fiitjee aits questions over here! you can get the answers from the solutions provided by fiitjee !
please don't mind this interference !
well buddy u know wat kinda a soln they hav.........
sample this
solution
Q1....A
Q2....C......................
finish....that kinda soln they hav
their sol booklets dont have solns ...in most qs they write they correct option number and even if they do hav they are not proper.....thats why im asking here
