why 3 rejected in question 8
Saare pagal ho.
Hat bsdk
Jethiyaaaaaaa!!!!!! Chhadi se maruun gaaa
Hahaha
Chup Saathvi Fail!!
kaise ho jetha ji
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

Hello everyone
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 😠
