What two numbers multiply to 424 and add up to -425?

Here we answer the question: "What two numbers multiply to 424 and add up to -425?"

The answer to your question is:

-424 and -1

Below we illustrate and prove that -424 and -1 multiply to 424 and add up to -425:

-424 × -1 = 424
-424 + -1 = -425

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

x² - 425x + 424 = 0

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

(x - 424 ) (x - 1)

To summarize, since -424 and -1 multiply to 424 and add up -425, you know that the following is true:

x² - 425x + 424 = (x - 424 ) (x - 1)
