BlakeDo you mean "what could you multiply to get 280 and add to get -27"? If so, then it can only be done with complex numbers:
ab = 280
a + b = -27
∴ b = -27 - a
∴ a(-27 - a) = 280
∴ -a2 - 27a = 280
∴ a2 + 27a + (27/2)2 = -280 + (27/2)2
∴ (a + 27/2)2 = -280 + 729/4
∴ (a + 27/2)2 = (729 - 1120)/4
∴ (a + 27/2)2 = -391/4
∴ a + 27/2 = ± i√391 / 2
∴ a = (-27 ± i√391) / 2
