What two numbers multiply to -320 and add up to 32?

Here we answer the question: "What two numbers multiply to -320 and add up to 32?"

The answer to your question is:

-8 and 40

Below we illustrate and prove that -8 and 40 multiply to -320 and add up to 32:

-8 × 40 = -320
-8 + 40 = 32

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

x² + 32x - 320 = 0

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

(x - 8 ) (x + 40)

To summarize, since -8 and 40 multiply to -320 and add up 32, you know that the following is true:

x² + 32x - 320 = (x - 8 ) (x + 40)
