Question

if alpha anb beta be the roots of equation: X2-px+q =0 and if Vn=@n+Bn prove that Vn+1=PVn-Qvn-1

Answer 1

???

Answer 2

what?

Answer 3

@dumbcow, can you make heads of tails of this?

Answer 4

HEY dumo..wht u wana say?

Answer 5

so if a,b is alpha and beta

then a,b are roots of x^2 -px+q
v = a+b

prove
v+1 = pv -qv -1

Answer 6

(x-a)(x-b) = x^2 -px +q
ab = q
a+b = p

--> a+b+1 = (a+b)^2 -ab(a+b) -1

??

Answer 7

hmm..
