What two numbers multiply to -622 and add up to 621?

Here we answer the question: "What two numbers multiply to -622 and add up to 621?"

The answer to your question is:

-1 and 622

Below we illustrate and prove that -1 and 622 multiply to -622 and add up to 621:

-1 × 622 = -622
-1 + 622 = 621

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

x² + 621x - 622 = 0

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

(x - 1 ) (x + 622)

To summarize, since -1 and 622 multiply to -622 and add up 621, you know that the following is true:

x² + 621x - 622 = (x - 1 ) (x + 622)
