What two numbers multiply to -779 and add up to 778?

Here we answer the question: "What two numbers multiply to -779 and add up to 778?"

The answer to your question is:

-1 and 779

Below we illustrate and prove that -1 and 779 multiply to -779 and add up to 778:

-1 × 779 = -779
-1 + 779 = 778

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

x² + 778x - 779 = 0

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

(x - 1 ) (x + 779)

To summarize, since -1 and 779 multiply to -779 and add up 778, you know that the following is true:

x² + 778x - 779 = (x - 1 ) (x + 779)
