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:

-96 and 5

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

-96 × 5 = -480
-96 + 5 = -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 - 96 ) (x + 5)

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

x² - 91x - 480 = (x - 96 ) (x + 5)
