What two numbers multiply to 622 and add up to -623?

Here we answer the question: "What two numbers multiply to 622 and add up to -623?"

The answer to your question is:

-622 and -1

Below we illustrate and prove that -622 and -1 multiply to 622 and add up to -623:

-622 × -1 = 622
-622 + -1 = -623

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

x² - 623x + 622 = 0

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

(x - 622 ) (x - 1)

To summarize, since -622 and -1 multiply to 622 and add up -623, you know that the following is true:

x² - 623x + 622 = (x - 622 ) (x - 1)
