.
Divide all the term by common factor 5 to get an equivalent equation in the simpler form


x^2 + 8x + 16 = 0.


Notice that it is


 = 0.


The equation has single root x= -4.


It is the case, when two real solutions merge into one sigle value.


Answer.  The given equation has the single root x= -4, which is an integer number.
