What two numbers multiply to -480 and add up to 91?

Here we answer the question: "What two numbers multiply to -480 and add up to 91?"

The answer to your question is:

-5 and 96

Below we illustrate and prove that -5 and 96 multiply to -480 and add up to 91:

-5 × 96 = -480
-5 + 96 = 91

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

x² + 91x - 480 = 0

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

(x - 5 ) (x + 96)

To summarize, since -5 and 96 multiply to -480 and add up 91, you know that the following is true:

x² + 91x - 480 = (x - 5 ) (x + 96)
