Here we answer the question: "What two numbers multiply to -340 and add up to -339?"

The answer to your question is:

-340 and 1

Below we illustrate and prove that -340 and 1 multiply to -340 and add up to -339:

-340 × 1 = -340
-340 + 1 = -339

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

x² - 339x - 340 = 0
