What two numbers multiply to -320 and add up to -76?

Here we answer the question: "What two numbers multiply to -320 and add up to -76?"

The answer to your question is:

-80 and 4

Below we illustrate and prove that -80 and 4 multiply to -320 and add up to -76:

-80 × 4 = -320
-80 + 4 = -76

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

x² - 76x - 320 = 0

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

(x - 80 ) (x + 4)

To summarize, since -80 and 4 multiply to -320 and add up -76, you know that the following is true:

x² - 76x - 320 = (x - 80 ) (x + 4)
