Question

Write two numbers that multiply to the value on top and add to the value on bottom.

Answer 1

Interpreting the top as 12×12 = 144 and the bottom as −8, you need two numbers whose product is 144 and whose sum is −8.

Let the numbers be t and u. Then
t + u = −8 and tu = 144.
t satisfies t^2 + 8t + 144 = 0, whose discriminant is 64 − 576 = −512, so there are no real (hence no integer) solutions.

The two complex solutions are
t,u = −4 ± 8i√2,
which do multiply to 144 and add to −8.

If you meant a different top or bottom, tell me and I’ll redo it.
