What two numbers multiply to -340 and add up to 339?

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

The answer to your question is:

-1 and 340

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

-1 × 340 = -340
-1 + 340 = 339

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

x² + 339x - 340 = 0

If so, the solution to factor the quadratic equation above is:

(x - 1 ) (x + 340)

To summarize, since -1 and 340 multiply to -340 and add up 339, you know that the following is true:

x² + 339x - 340 = (x - 1 ) (x + 340)
