What two numbers multiply to -768 and add up to 767?

Here we answer the question: "What two numbers multiply to -768 and add up to 767?"

The answer to your question is:

-1 and 768

Below we illustrate and prove that -1 and 768 multiply to -768 and add up to 767:

-1 × 768 = -768
-1 + 768 = 767

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

x² + 767x - 768 = 0

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

(x - 1 ) (x + 768)

To summarize, since -1 and 768 multiply to -768 and add up 767, you know that the following is true:

x² + 767x - 768 = (x - 1 ) (x + 768)
