What two numbers multiply to 403 and add up to -404?

Here we answer the question: "What two numbers multiply to 403 and add up to -404?"

The answer to your question is:

-403 and -1

Below we illustrate and prove that -403 and -1 multiply to 403 and add up to -404:

-403 × -1 = 403
-403 + -1 = -404

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

x² - 404x + 403 = 0

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

(x - 403 ) (x - 1)

To summarize, since -403 and -1 multiply to 403 and add up -404, you know that the following is true:

x² - 404x + 403 = (x - 403 ) (x - 1)
