Here we answer the question: "What two numbers multiply to -878 and add up to 437?"

The answer to your question is:

-2 and 439

Below we illustrate and prove that -2 and 439 multiply to -878 and add up to 437:

-2 × 439 = -878
-2 + 439 = 437

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 437x - 878 = 0
