Just write it in factorial form and then you'll get a equation like this
8n^2 -96n + 88 = 0
Divide throughout by 8 you'll get
n^2 - 12n + 11 = 0
Then calculate factors of 'n' you will get
(n-11)(n-1) = 0
Which is n= 11 and n = 1
As n = 1 is not possible so final answer is n = 11
8n^2 -96n + 88 = 0
Divide throughout by 8 you'll get
n^2 - 12n + 11 = 0
Then calculate factors of 'n' you will get
(n-11)(n-1) = 0
Which is n= 11 and n = 1
As n = 1 is not possible so final answer is n = 11
