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.

Somewhat beyond the typical Algebra I answer, but if you want to have an irreducible factorization then:

`2n^2+34n+125=0`   (divided by 2)

`Delta= 1156- 4xx2xx125=156 >0`  has two solution:


`x=(-34+-2sqrt(39))/2` `=-17+-sqrt(39)`

So:  `4n^2+68n+250=` `2(n+17+sqrt(39))(n+17-sqrt(39))`
