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:

-3 and 140

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

-3 × 140 = -420
-3 + 140 = 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 - 3 ) (x + 140)

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

x² + 137x - 420 = (x - 3 ) (x + 140)
