What two numbers multiply to -637 and add up to 636?

Here we answer the question: "What two numbers multiply to -637 and add up to 636?"

The answer to your question is:

-1 and 637

Below we illustrate and prove that -1 and 637 multiply to -637 and add up to 636:

-1 × 637 = -637
-1 + 637 = 636

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

x² + 636x - 637 = 0

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

(x - 1 ) (x + 637)

To summarize, since -1 and 637 multiply to -637 and add up 636, you know that the following is true:

x² + 636x - 637 = (x - 1 ) (x + 637)
