What two numbers multiply to -782 and add up to 389?

Here we answer the question: "What two numbers multiply to -782 and add up to 389?"

The answer to your question is:

-2 and 391

Below we illustrate and prove that -2 and 391 multiply to -782 and add up to 389:

-2 × 391 = -782
-2 + 391 = 389

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

x² + 389x - 782 = 0

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

(x - 2 ) (x + 391)

To summarize, since -2 and 391 multiply to -782 and add up 389, you know that the following is true:

x² + 389x - 782 = (x - 2 ) (x + 391)
