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:

-40 and 8

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

-40 × 8 = -320
-40 + 8 = -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 - 40 ) (x + 8)

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

x² - 32x - 320 = (x - 40 ) (x + 8)
