What two numbers multiply to -720 and add up to -48?

Here we answer the question: "What two numbers multiply to -720 and add up to -48?"

The answer to your question is:

-60 and 12

Below we illustrate and prove that -60 and 12 multiply to -720 and add up to -48:

-60 × 12 = -720
-60 + 12 = -48

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

x² - 48x - 720 = 0

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

(x - 60 ) (x + 12)

To summarize, since -60 and 12 multiply to -720 and add up -48, you know that the following is true:

x² - 48x - 720 = (x - 60 ) (x + 12)
