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:

-2 and 406

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

-2 × 406 = -812
-2 + 406 = 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 - 2 ) (x + 406)

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

x² + 404x - 812 = (x - 2 ) (x + 406)
