system%28xy=-12%2Cx%2By=-1%29

y=-x-1
-
x%28-x-1%29=-12
x%28x%2B1%29=12
no real need to use other algebra from here.
two numbers differ by 1, product is 12
3%284%29=12

But to get the negatives, numbers are 3 and -4.

Note, Also For Factorization:
-x%5E2-x=-12
x%5E2%2Bx=12
x%5E2%2Bx-12=0
%28x-3%29%28x%2B4%29=0

x is 3 and the other number is -4.
