Question

n(2n-1)=k(2k-1)+(4k+1)
WHERE , k+1=n,
make the right hand side equal to left hand side......
please.....

Answer 1

is that the full question ?

Answer 2

YES

Answer 3

Like is that the beginning of the question ? since it doesn't make sense ?

Answer 4

an equation is :
n(2n-1)=k(2k-1)+(4k+1)
and k+1=n is given,
now i want to make right hand side equal to left hand side

Answer 5

please

Answer 6

can you understand ?

Answer 7

well, are you sure that its right ?

it might be n(2n-1) = n(2k-1) + (4n+1)

im not sure.

Answer 8

what does the first question say ?

Answer 9

this is mathematical induction btw

Answer 10

an equation is given n(2n-1)=k(2k-1)+(4k+1)
and it is asking to make the R.H.S. equal to L.H.S.
and it is given k+1=n

Answer 11

now we have to prove R.H.S

Answer 12

WE DONT HAVE TO TOUCH L.H.S.

Answer 13

well, the question is stated weirdly but anyway

(k+1)(2k+1) = k(2k-1)+(4k+1)

2k^2 + 3k + 1 = 2k^2 - k + 4k + 1

2k^2 + 3k + 1 = 2k^2 + 3k + 1

There for RHS=LHS

Answer 14

no the question is to make: n(2n-1)=n(2n-1)

Answer 15

n(2n-1) = n(2n-1) ???

This is mathematical induction i think, you can just expand and prove it

Answer 16

this is given :
n(2n-1)=k(2k-1)+(4k+1)
we have to make it :
n(2n-1) = n(2n-1)
and a value is given :
k+1=n

Answer 17

?

Answer 18

Hm, well the question is worded weirdly to me, the way i did it was correct to prove RHS=LHS.

Hopefully, someoone else would be able to help you sorry.

Answer 19

no problem , i am very thankfull to you for your kindness and time !!!
you tried to help me , this is great to me .....
