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

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

The answer to your question is:

-621 and -1

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

-621 × -1 = 621
-621 + -1 = -622

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

x² - 622x + 621 = 0

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

(x - 621 ) (x - 1)

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

x² - 622x + 621 = (x - 621 ) (x - 1)
