What two numbers multiply to -804 and add up to -400?

Here we answer the question: "What two numbers multiply to -804 and add up to -400?"

The answer to your question is:

-402 and 2

Below we illustrate and prove that -402 and 2 multiply to -804 and add up to -400:

-402 × 2 = -804
-402 + 2 = -400

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

x² - 400x - 804 = 0

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

(x - 402 ) (x + 2)

To summarize, since -402 and 2 multiply to -804 and add up -400, you know that the following is true:

x² - 400x - 804 = (x - 402 ) (x + 2)
