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:

-4 and 200

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

-4 × 200 = -800
-4 + 200 = 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 - 4 ) (x + 200)

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

x² + 196x - 800 = (x - 4 ) (x + 200)
