What two numbers multiply to -420 and add up to -137?

Here we answer the question: "What two numbers multiply to -420 and add up to -137?"

The answer to your question is:

-140 and 3

Below we illustrate and prove that -140 and 3 multiply to -420 and add up to -137:

-140 × 3 = -420
-140 + 3 = -137

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

x² - 137x - 420 = 0

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

(x - 140 ) (x + 3)

To summarize, since -140 and 3 multiply to -420 and add up -137, you know that the following is true:

x² - 137x - 420 = (x - 140 ) (x + 3)
