What two numbers multiply to -480 and add up to 238?

Here we answer the question: "What two numbers multiply to -480 and add up to 238?"

The answer to your question is:

-2 and 240

Below we illustrate and prove that -2 and 240 multiply to -480 and add up to 238:

-2 × 240 = -480
-2 + 240 = 238

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

x² + 238x - 480 = 0

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

(x - 2 ) (x + 240)

To summarize, since -2 and 240 multiply to -480 and add up 238, you know that the following is true:

x² + 238x - 480 = (x - 2 ) (x + 240)
