What two numbers multiply to -320 and add up to -59?

Here we answer the question: "What two numbers multiply to -320 and add up to -59?"

The answer to your question is:

-64 and 5

Below we illustrate and prove that -64 and 5 multiply to -320 and add up to -59:

-64 × 5 = -320
-64 + 5 = -59

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

x² - 59x - 320 = 0

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

(x - 64 ) (x + 5)

To summarize, since -64 and 5 multiply to -320 and add up -59, you know that the following is true:

x² - 59x - 320 = (x - 64 ) (x + 5)
