What two numbers multiply to -782 and add up to 781?

Here we answer the question: "What two numbers multiply to -782 and add up to 781?"

The answer to your question is:

-1 and 782

Below we illustrate and prove that -1 and 782 multiply to -782 and add up to 781:

-1 × 782 = -782
-1 + 782 = 781

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

x² + 781x - 782 = 0

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

(x - 1 ) (x + 782)

To summarize, since -1 and 782 multiply to -782 and add up 781, you know that the following is true:

x² + 781x - 782 = (x - 1 ) (x + 782)
