What two numbers multiply to -278 and add up to 137?

Here we answer the question: "What two numbers multiply to -278 and add up to 137?"

The answer to your question is:

-2 and 139

Below we illustrate and prove that -2 and 139 multiply to -278 and add up to 137:

-2 × 139 = -278
-2 + 139 = 137

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

x² + 137x - 278 = 0

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

(x - 2 ) (x + 139)

To summarize, since -2 and 139 multiply to -278 and add up 137, you know that the following is true:

x² + 137x - 278 = (x - 2 ) (x + 139)
