What two numbers multiply to 842 and add up to -423?

Here we answer the question: "What two numbers multiply to 842 and add up to -423?"

The answer to your question is:

-421 and -2

Below we illustrate and prove that -421 and -2 multiply to 842 and add up to -423:

-421 × -2 = 842
-421 + -2 = -423

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

x² - 423x + 842 = 0

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

(x - 421 ) (x - 2)

To summarize, since -421 and -2 multiply to 842 and add up -423, you know that the following is true:

x² - 423x + 842 = (x - 421 ) (x - 2)
