What two numbers multiply to -385 and add up to -48?

Here we answer the question: "What two numbers multiply to -385 and add up to -48?"

The answer to your question is:

-55 and 7

Below we illustrate and prove that -55 and 7 multiply to -385 and add up to -48:

-55 × 7 = -385
-55 + 7 = -48

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

x² - 48x - 385 = 0

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

(x - 55 ) (x + 7)

To summarize, since -55 and 7 multiply to -385 and add up -48, you know that the following is true:

x² - 48x - 385 = (x - 55 ) (x + 7)
