What two numbers multiply to -626 and add up to 625?

Here we answer the question: "What two numbers multiply to -626 and add up to 625?"

The answer to your question is:

-1 and 626

Below we illustrate and prove that -1 and 626 multiply to -626 and add up to 625:

-1 × 626 = -626
-1 + 626 = 625

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

x² + 625x - 626 = 0

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

(x - 1 ) (x + 626)

To summarize, since -1 and 626 multiply to -626 and add up 625, you know that the following is true:

x² + 625x - 626 = (x - 1 ) (x + 626)
