What two numbers multiply to -625 and add up to 624?

Here we answer the question: "What two numbers multiply to -625 and add up to 624?"

The answer to your question is:

-1 and 625

Below we illustrate and prove that -1 and 625 multiply to -625 and add up to 624:

-1 × 625 = -625
-1 + 625 = 624

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

x² + 624x - 625 = 0

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

(x - 1 ) (x + 625)

To summarize, since -1 and 625 multiply to -625 and add up 624, you know that the following is true:

x² + 624x - 625 = (x - 1 ) (x + 625)
