wat did u assume??
by chance same as what deedeedudu assumed :)

Q3f(2x-1) = 3x +4 , what is the value of f(1) +f(2)+ f(3)......f(10)a) 130b) 137.5c)145d) 150
OPTION B
f(1)=3+4
f(2)=4.5+4
....

SUM= 10(4) + 5(6+13.5)
137.5

Take Alpha=2,Bita=1/2,Gaama=3, Delta =1/3
why 2,1/2,3,1/3 ?? :banghead:

why not 1,2,3,5 or anyother distinct roots ?
3805
@techsurge we can do it assuming 11 th term square to be 2 and 5th term square term to be 1 .

PS question give us liberty to assume any value since variable p is involved.

bhai ab = 1 he na so reciprocal roots ayenge..same for othr equation

Product 1 chahiye just to make life easy assume easiest values :)

bot possible const =1
3809
@gs4890 in both of the equation pdt of root is 1 thats y
3810
@gs4890 Bhai Product of roots need to be 1 .Your last constant term is given t be 1.
