What two numbers multiply to -631 and add up to 630?

Here we answer the question: "What two numbers multiply to -631 and add up to 630?"

The answer to your question is:

-1 and 631

Below we illustrate and prove that -1 and 631 multiply to -631 and add up to 630:

-1 × 631 = -631
-1 + 631 = 630

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

x² + 630x - 631 = 0

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

(x - 1 ) (x + 631)

To summarize, since -1 and 631 multiply to -631 and add up 630, you know that the following is true:

x² + 630x - 631 = (x - 1 ) (x + 631)
