What two numbers multiply to -636 and add up to 635?

Here we answer the question: "What two numbers multiply to -636 and add up to 635?"

The answer to your question is:

-1 and 636

Below we illustrate and prove that -1 and 636 multiply to -636 and add up to 635:

-1 × 636 = -636
-1 + 636 = 635

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

x² + 635x - 636 = 0

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

(x - 1 ) (x + 636)

To summarize, since -1 and 636 multiply to -636 and add up 635, you know that the following is true:

x² + 635x - 636 = (x - 1 ) (x + 636)
