Saare pagal ho.

Hahaha

Chup Saathvi Fail!!

can anyone explain me 7th answer how this step is derivated in answer An+2-2An/2An+1 =3

i dont know if u will read this or not but here your answer

x2=6x+2

alpha2=6alpha+2———1

multiply eq1 by alpha^8

alpha^10=6alpha^9+2alpha^8

do the same with bheta and name the eq 2 and then subtract eq 2 from 1

you will get

alpha10-bheta10=alpha9-bheta9+alpha8-bheta8

which will be equal an=alpha^n-bheta^n

a10=6a9+2a8

a10-2a8=6a9

a10-2a8/2a9=3

you welcome

Bhai/bahan itna bhi nahi aata. Chullu bhr pani m duub mr.

Alright . Why we didn’t consider 3 in 8 question although it’s satisfying the equation? Any one pls

Well, 3 is a solution for x^2 – 5x + 5 = -1, right so the quadratic is power that is X^2 + 4x – 60 should be even as (-1)^even number = 1 and (-1)^odd number = -1. Putting x = 3 in X^2 + 4x – 60 gives and odd number. Hence 3 is rejected.

Realy very good question

where to get more questions sirr

same question

Not bad but, I need clear explanation of why 3 is not included in solution of question number 8

bcs when u substitute it in power ,comes out odd and gives -1

Give some many questions

Scary

I don’t want to leave anything 😠
