What two numbers multiply to -939 and add up to 310?

Here we answer the question: "What two numbers multiply to -939 and add up to 310?"

The answer to your question is:

-3 and 313

Below we illustrate and prove that -3 and 313 multiply to -939 and add up to 310:

-3 × 313 = -939
-3 + 313 = 310

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

x² + 310x - 939 = 0

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

(x - 3 ) (x + 313)

To summarize, since -3 and 313 multiply to -939 and add up 310, you know that the following is true:

x² + 310x - 939 = (x - 3 ) (x + 313)
