What two numbers multiply to -800 and add up to -196?

Here we answer the question: "What two numbers multiply to -800 and add up to -196?"

The answer to your question is:

-200 and 4

Below we illustrate and prove that -200 and 4 multiply to -800 and add up to -196:

-200 × 4 = -800
-200 + 4 = -196

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

x² - 196x - 800 = 0

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

(x - 200 ) (x + 4)

To summarize, since -200 and 4 multiply to -800 and add up -196, you know that the following is true:

x² - 196x - 800 = (x - 200 ) (x + 4)
