Question

squareroot of 2n squared - 121 = a

pls help
pls answer .

Answer 1

What are you trying to find out?

Answer 2

radical equation .

Answer 3

So you have \[\sqrt{2n^2-121}=a\] Correct?

Answer 4

yes

Answer 5

\[n = \pm \sqrt{(a^2 + 121)/2}\]

Answer 6

whats the solution and answer pls .

Answer 7

what are you solving for? n? a? or are you factorizing?

Answer 8

Can you write out the complete question?

Answer 9

What kind of solution ?

Answer 10

yes i am looking for n .
squareroot of 2n^2 - n-=a

Answer 11

a = -1/8 n = 1/4

Answer 12

How did you get that answer Aron West?

Answer 13

a = 2 m^2+m, n = -m, \[a = 2 m^2+m, n = -m, m \to \mathbb{Z}^+\]

Answer 14

Sorry I don't follow, could you expand on this?

Answer 15

tnx

Answer 16

ALSO, \[n = 1/4(1 \pm \sqrt{8a +1})\]
