What two numbers multiply to -480 and add up to 157?

Here we answer the question: "What two numbers multiply to -480 and add up to 157?"

The answer to your question is:

-3 and 160

Below we illustrate and prove that -3 and 160 multiply to -480 and add up to 157:

-3 × 160 = -480
-3 + 160 = 157

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

x² + 157x - 480 = 0

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

(x - 3 ) (x + 160)

To summarize, since -3 and 160 multiply to -480 and add up 157, you know that the following is true:

x² + 157x - 480 = (x - 3 ) (x + 160)
