(3-x) is the right ans.
use the basic theorem
"If a polynomial f(x) be divided by (x - a), the remainder is f(a)."
so we hav f(1)=2 and f(2)=1
now,f(x)= p(x)*(x-1)(x-2) + r(x) ;(r(x) is remainder,also degree of r(x)< degree of p(x) )
put x=1; f(1)= r(1)=2
x=2; f(2)=r(2)=1
so...

ans (5)
AB^2= 20cm2
for the benefit of all puys i hav attached the year 2007 and 2008 QQAD set(with ans) & QQAD 2008 practice set .

1) ans (a)
D= 4a(a-6)
and to have distinct roots D>0 so we get a>6 or a<0
so option 2 can be ruled out.
now,x= -(a-3)+-sqrt (a*(a-6))
put x> 6 and this doesn't satisfie the condition so we r left with only 1 option and that's a<-3/4
so ans a.
2) D=8a-8
for root to be real ...

yup..u got it.
ans is 2 min

1) work done by trio in 1 day =1/2(1/4 +1/6 +1/10) =31/120
so total days to complete the work = 120/31
2) tank filled in 1 min = 3*1/120 -1/180 = 7/360
so after 360/7 min tank wil start overflowing.
3) still working on......

It surely loads faster and now i don't need to reload every page(as was case of earlier).it's a great relief.
and yes like many puys i m also not feeling comfy wid colour combination .
particularly Thank! and Groan! ka color

it's given that "not necessarily equal angles" .that doesn't mean that not equal angles.
but i think in case of not equal angle we can't decide the side length.
toxic replied to official quant thread for CAT 2009
suppose pentagon has unequal angles.in this case pentagon wil be a concave pentagon(as it has eual sides so convex pentagon isn't possible).and then ans wil change......
take case of conclave pentagon(like "Draw an equilateral triangle.....draw a square with the base of triangle as its side......
