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:

-320 and 1

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

-320 × 1 = -320
-320 + 1 = -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 - 320 ) (x + 1)

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

x² - 319x - 320 = (x - 320 ) (x + 1)
