What two numbers multiply to 422 and add up to -423?

Here we answer the question: "What two numbers multiply to 422 and add up to -423?"

The answer to your question is:

-422 and -1

Below we illustrate and prove that -422 and -1 multiply to 422 and add up to -423:

-422 × -1 = 422
-422 + -1 = -423

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

x² - 423x + 422 = 0

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

(x - 422 ) (x - 1)

To summarize, since -422 and -1 multiply to 422 and add up -423, you know that the following is true:

x² - 423x + 422 = (x - 422 ) (x - 1)
