What two numbers multiply to -808 and add up to -402?

Here we answer the question: "What two numbers multiply to -808 and add up to -402?"

The answer to your question is:

-404 and 2

Below we illustrate and prove that -404 and 2 multiply to -808 and add up to -402:

-404 × 2 = -808
-404 + 2 = -402

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

x² - 402x - 808 = 0

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

(x - 404 ) (x + 2)

To summarize, since -404 and 2 multiply to -808 and add up -402, you know that the following is true:

x² - 402x - 808 = (x - 404 ) (x + 2)
