Question

If a,b are roots of x2+px+1=0 c,d are roots of x2+qx+1=0 then (a-c)(b-c)(a+d)(b+d)

Answer 1

Answer:

let the a be the alfa and the b be the beta

now given equation is x²+qx+1=o

comparing the given equation with ax²+bx+c=0

we get,

a=1,b=1,c=1

now,

Alfa+beta= -b/a

= -1/1

=1

now,

alfa×beta=c/a

=1/1

=1

ans_a and b are the roots of given equation
