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:

-160 and 3

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

-160 × 3 = -480
-160 + 3 = -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 - 160 ) (x + 3)

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

x² - 157x - 480 = (x - 160 ) (x + 3)
