Answer 2

Since you have unknown coefficients of x, you're only able to express it in terms of its coefficients (or, as shown below, as 0).
Therefore:
x = (-t ± √(t²-4n*0))/-2n
= (-t±t)/-2n
so x = (-t+t)/-2n = 0
or x = (-t-t)/-2n = -2t/-2n = t/n

Answer 3

Since you have unknown coefficients of x, you're only able to express it in terms of its coefficients (or, as shown below, as 0).
Therefore:
x = (-t ± √(t²-4n*0))/-2n
= (-t±t)/-2n
so x = (-t+t)/-2n = 0
or x = (-t-t)/-2n = -2t/-2n = t/n
