What two numbers multiply to 402 and add up to -403?

Here we answer the question: "What two numbers multiply to 402 and add up to -403?"

The answer to your question is:

-402 and -1

Below we illustrate and prove that -402 and -1 multiply to 402 and add up to -403:

-402 × -1 = 402
-402 + -1 = -403

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

x² - 403x + 402 = 0

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

(x - 402 ) (x - 1)

To summarize, since -402 and -1 multiply to 402 and add up -403, you know that the following is true:

x² - 403x + 402 = (x - 402 ) (x - 1)
