What two numbers multiply to -480 and add up to 38?

Here we answer the question: "What two numbers multiply to -480 and add up to 38?"

The answer to your question is:

-10 and 48

Below we illustrate and prove that -10 and 48 multiply to -480 and add up to 38:

-10 × 48 = -480
-10 + 48 = 38

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

x² + 38x - 480 = 0

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

(x - 10 ) (x + 48)

To summarize, since -10 and 48 multiply to -480 and add up 38, you know that the following is true:

x² + 38x - 480 = (x - 10 ) (x + 48)
