If you are factoring a trinomial, and aren't studying complex numbers, you are very close, but need to look at the problem again. Are they supposed to multiply to give you 180 or -180? With real numbers, 180 doesn't work, but -180 does.

-15 X 12 = -180 and -15 + 12 = -3

15 X -12 = -180 and 15 + -12 = 3

If we take your question exactly as you wrote it, then there are

no two real numbers that satisfy that description.

The only numbers that can do it are the pair of complex conjugates

1.5 ± 13.3323 i (rounded)
