What two numbers multiply to -320 and add up to 319?

Here we answer the question: "What two numbers multiply to -320 and add up to 319?"

The answer to your question is:

-1 and 320

Below we illustrate and prove that -1 and 320 multiply to -320 and add up to 319:

-1 × 320 = -320
-1 + 320 = 319

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

x² + 319x - 320 = 0

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

(x - 1 ) (x + 320)

To summarize, since -1 and 320 multiply to -320 and add up 319, you know that the following is true:

x² + 319x - 320 = (x - 1 ) (x + 320)
