chhoriye ! i think i will go and sleep :P :P :P

my mind is like the line of your fourth graph n wat ever you said is getting like the curve :'(

oooooooo :'(

hmmmmm... i think both the cases will have the case c=0 also.... which i took to be >0 [silly me [3]]

but bhaiya[any one]... pls rep......

sky think in terms of graph...

then see the parabola..

the parabola goes upwards so there will be no root for large lamda

Lokesh Verma ·

For very different values of lamda... the graph will change like shown in the figure below (for case when a>0)

62
Lokesh Verma ·

sky you have urself said that for small lamda in first case

so that means that if lamda becomes large then it is not possible at all tha tthe graph cuts the x axis.. thus no real roots :)

ax2+bx+c + λ =0

condition : two disticnt positive roots.

let they be α n β .

so, α+β>0 and αβ >0

=> b/a < 0 and c+λ / a >0

b +ve, a -ve => c+λ ...-ve => if λ>0, c<0 ; if λ<0, c can be <0 or>0. [so three cases]

b -ve, a +ve => c+λ ... +ve => if λ>0, c>0 or c<0 ; if λ<0, c>0 [again three cases here]

so is the ans six ??

see it is said that for all lamda :)

but yeah dont stress your mind a lot :)

answer for your polynomial question is (A)

1
Philip Calvert ·

yes akand was spot on i think

degree of divisor = 4

so degree of remainder = 2007 % 4 = 3

i dont know why noone paid attention to this

1
Philip Calvert ·

for two distinct positive roots

first of all D > 0

then as sky said α+β > 0

and f(0) > 0

since not much is given about a b and c i dont get how to get the answer

~AjInKyA~ ·

degree ?
n of remainder?
i think so , its
1 c
is it ?

Can the first one be done with the help of Complex numbers???

msp ·

for the second qn is it c

1
~AjInKyA~ ·

then
c ?

ANKIT GOYAL ·

then acc to sky the constant term 1 would be cancelled and the reminder must come zero..................

I think so is it rite

1
~AjInKyA~ ·

but in 2nd one,
it depends whether original has how many
roots ?
then only v can tell bout new eqn naaaaaaa ?

(x2+1)(x2+x+1)
= (x2+1)(x3-1)/ (x-1)

x2007-1
= [(x3-1) + 1]669 - 1
=k (x3 -1)

try this way ....

ghum pachhe :P

2nd

answer is C?

1
~AjInKyA~ ·

2nd one
i think lamba must b zero
so 1
A
?RIGHT?

1
Akand ·

x2007 and maximum degree of divisor is x4....

so x4 can divide only till 2004...
so 2007=2004+3

so x3 remains....

soo degree is 3...

IS MY THINKIN crt?

11
Mani Pal Singh ·

bhai write this in the form

[(x3)669-1]
[(x3)3 X 223-1]

u know that x3-1=(x-1)(x2+x+1)

[(x3)3 X 223-1](x-1)
-------------------
x2+1(x2+x+1)(x-1)

yaar last mein x ko kuch daal de
upper niche kaaatne ke baad

1
~AjInKyA~ ·

i still think c of 1st

1
~AjInKyA~ ·

oh
u mean
put any value of x
that remainder must be
then watever left ,say 1000 or 27 ? to be perfect cubes
wod b remainder?
is my thinkin crt ?
