What two numbers multiply to -682 and add up to 681?

Here we answer the question: "What two numbers multiply to -682 and add up to 681?"

The answer to your question is:

-1 and 682

Below we illustrate and prove that -1 and 682 multiply to -682 and add up to 681:

-1 × 682 = -682
-1 + 682 = 681

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

x² + 681x - 682 = 0

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

(x - 1 ) (x + 682)

To summarize, since -1 and 682 multiply to -682 and add up 681, you know that the following is true:

x² + 681x - 682 = (x - 1 ) (x + 682)
