What two numbers multiply to -635 and add up to 634?

Here we answer the question: "What two numbers multiply to -635 and add up to 634?"

The answer to your question is:

-1 and 635

Below we illustrate and prove that -1 and 635 multiply to -635 and add up to 634:

-1 × 635 = -635
-1 + 635 = 634

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

x² + 634x - 635 = 0

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

(x - 1 ) (x + 635)

To summarize, since -1 and 635 multiply to -635 and add up 634, you know that the following is true:

x² + 634x - 635 = (x - 1 ) (x + 635)
