What two numbers multiply to -480 and add up to 14?

Here we answer the question: "What two numbers multiply to -480 and add up to 14?"

The answer to your question is:

-16 and 30

Below we illustrate and prove that -16 and 30 multiply to -480 and add up to 14:

-16 × 30 = -480
-16 + 30 = 14

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

x² + 14x - 480 = 0

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

(x - 16 ) (x + 30)

To summarize, since -16 and 30 multiply to -480 and add up 14, you know that the following is true:

x² + 14x - 480 = (x - 16 ) (x + 30)
