What two numbers multiply to -200 and add up to -199?

Here we answer the question: "What two numbers multiply to -200 and add up to -199?"

The answer to your question is:

-200 and 1

Below we illustrate and prove that -200 and 1 multiply to -200 and add up to -199:

-200 × 1 = -200
-200 + 1 = -199

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

x² - 199x - 200 = 0

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

(x - 200 ) (x + 1)

To summarize, since -200 and 1 multiply to -200 and add up -199, you know that the following is true:

x² - 199x - 200 = (x - 200 ) (x + 1)
