Here we answer the question: "What two numbers multiply to 804 and add up to -404?"
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 -404:
-402 × -2 = 804
-402 + -2 = -404
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 404x + 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 -404, you know that the following is true:
x2 - 404x + 804 = (x - 402 ) (x - 2)
