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:

-5 and 64

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

-5 × 64 = -320
-5 + 64 = 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 - 5 ) (x + 64)

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

x² + 59x - 320 = (x - 5 ) (x + 64)
