What two numbers multiply to -812 and add up to -404?

Here we answer the question: "What two numbers multiply to -812 and add up to -404?"

The answer to your question is:

-406 and 2

Below we illustrate and prove that -406 and 2 multiply to -812 and add up to -404:

-406 × 2 = -812
-406 + 2 = -404

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

x² - 404x - 812 = 0

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

(x - 406 ) (x + 2)

To summarize, since -406 and 2 multiply to -812 and add up -404, you know that the following is true:

x² - 404x - 812 = (x - 406 ) (x + 2)
