What two numbers multiply to 320 and add up to -48?

Here we answer the question: "What two numbers multiply to 320 and add up to -48?"

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 -48:

-40 × -8 = 320
-40 + -8 = -48

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

x² - 48x + 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 -48, you know that the following is true:

x² - 48x + 320 = (x - 40 ) (x - 8)
