What two numbers multiply to -200 and add up to -10?

Here we answer the question: "What two numbers multiply to -200 and add up to -10?"

The answer to your question is:

-20 and 10

Below we illustrate and prove that -20 and 10 multiply to -200 and add up to -10:

-20 × 10 = -200
-20 + 10 = -10

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

x² - 10x - 200 = 0

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

(x - 20 ) (x + 10)

To summarize, since -20 and 10 multiply to -200 and add up -10, you know that the following is true:

x² - 10x - 200 = (x - 20 ) (x + 10)
