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:

-7 and 55

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

-7 × 55 = -385
-7 + 55 = 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 - 7 ) (x + 55)

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

x² + 48x - 385 = (x - 7 ) (x + 55)
