I used the same formula! I got around 80's
3 marks for the question, at least two on the pattern! There goes another one mark!

then you must have messed up in calcultaion or with the co-ordinates.

tum logo k Q (-15, 13) araha tha.. ??

I dont remeber mine, but it wasn't -15!

P k cordiants 3,1 ??

 

[Fallen316]

P k cordiants 3,1 ??

yuppio

 

[Fallen316]

yaar mein ne suna hai ye formula syllabus mein nhe.. ?? :-/

bakwas
koi bhi formula maar do

 

[Fallen316]

any possible stupid explanation for that ?

den i showed simple formula 1/2 x base x heitgh

 

[Fallen316]

den i showed simple formula 1/2 x base x heitgh

wo b theek hai .
the paper was easy but lengthy as well as tricky.

Fallen316 or Dukeofwin or MustafaMotani, if you have time to solve this question, plz do it:
"Show that the solutions of the equation x^2+kx=3-k are real for all real values of k."

bring k to the other side
x^2+kx+(-3+k) = 0
ab use b^2-4ac > 0

yar i used the formula
A = 1/2 | x1y1 x2y2 x3y3 x1y1 |
and the answer was 100 something.

i used the same formula but got 11!

ks ks ka part c lambda ke sath arha tha?????????

 

[MustafaMotani]

ks ks ka part c lambda ke sath arha tha?????????

mera

 

[Fallen316]

i used the same formula but got 11!

1. calculation error
2. wrong co-ordinates
co-ordinates were
P (3,1)
B ( were given )
Q (-15,13)
abhi beth kar solve karo sahi answer aaye ga

yar wo bgher lambda ke nkal hi nae rha tha wat were ur values for lmbda and mew?

tumharay 3rd part mein aya tha lambda ??

 

[Haris Bin Zahid]

bring k to the other side
x^2+kx+(-3+k) = 0
ab use b^2-4ac > 0

Yeah I did it, the discriminant is (k^2-4k+12).
Now what to do?

what was your are of tri mine was near 156!!!!!

 

[MustafaMotani]

yar wo bgher lambda ke nkal hi nae rha tha wat were ur values for lmbda and mew?

lambda 10/11 mew 4/15

 

[MustafaMotani]

what was your are of tri mine was near 156!!!!!

m9 was exactly 156
