Factor `4n^2+68n+250` :
`2(2n^2+34n+125)` factor out greatest common factor
This will not factor further in the rationals. The discriminant is 156 which is not a perfect square.

`2n^2+34n+125=0` (divided by 2)
`Delta= 1156- 4xx2xx125=156 >0` has two solution:
So: `4n^2+68n+250=` `2(n+17+sqrt(39))(n+17-sqrt(39))`
