Any help would be greatly appreciated.
Correct, but it is not a good idea to use "a" to represent two different quantities!
Perhaps it would be better to write
"The roots to the equation are . For this problem, i= 1, j= (a-1)/a, k= -1".
(I am assuming that in the first post, "a- 1/a" meant "(a-1)/a", not "a- (1/a)".)
