What two numbers multiply to -339 and add up to 338?

Here we answer the question: "What two numbers multiply to -339 and add up to 338?"

The answer to your question is:

-1 and 339

Below we illustrate and prove that -1 and 339 multiply to -339 and add up to 338:

-1 × 339 = -339
-1 + 339 = 338

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

x² + 338x - 339 = 0

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

(x - 1 ) (x + 339)

To summarize, since -1 and 339 multiply to -339 and add up 338, you know that the following is true:

x² + 338x - 339 = (x - 1 ) (x + 339)
