   where u all gone.......................... pls help meeeeeeeeee

 pls reply..........................

which is better ip(parshuram) or jaypee(guna)?????????

 pls reply

 the roots of the equation

  (3-x)⁴+(2-x)⁴=(5-2x)⁴   are

(A) all real                          (B) all imaginary                     (C) two imaginary and two real

(D) none

Let n be an odd postive integer such that  the polynomial 

P_n(x)=1+2x+3x²+......................+(n+1)xⁿ  has exactly one real root. This real root a satisfies

(A) -1<a<0               (B) 0<a<1                    (C) 0<=a<=1                         (D) -1<=a<=0

pls also tell me the proccess      

 Let n be ab odd postive integer. Then the number of real roots of the polynomial 

P_n(x)=1+2x+3x²+......................+(n+1)xⁿ is

(A) 0                   (B) n                    (C) 1                             (D) none

pls also tell me the proccess      

 how many roots does the equation possess?

        3^|x|.|2-|x||=1

(A) 1                                            (B) 2                                  (C) 3                           (D)  4

pls tell me the process

                                                           GENERAL

 My AIR in aieee is 88437 and state rank is 8000(delhi)....           my councelling is 2morrow..............................

should i go for the councelling or not..........

 how will we come to know that we have to impose the condition f(0)>0??

 

 someone pls answer........................

if it would have been like this

      x²-2(4k-1)x+15k²-2k-7<0

 then D>0??????

no it's (b)

               why  D<0?????
