-----------------
x + y = -5
x*y = -36
--------
Substitute for "x" and solve for "y"::
(-5-y)y = -36
---------------------
(5+y)y = 36
y^2 + 5y - 36 = 0
-------------------------
(y+9)(y-4) = 0
------------------
y = -9 and x = 4

let them be a and b
a+b=-5
ab=-36
a=-5-b
substitute
(-5-b)(b)=-36
-5b-b2^=-36
multiply by -1
b^2+5b=36
b^2+5b-36=0
(b+9)(b-4)=0
b=-9, 4
Those are the two integers
