What two numbers multiply to -861 and add up to -20?

Here we answer the question: "What two numbers multiply to -861 and add up to -20?"

The answer to your question is:

-41 and 21

Below we illustrate and prove that -41 and 21 multiply to -861 and add up to -20:

-41 × 21 = -861
-41 + 21 = -20

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

x² - 20x - 861 = 0

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

(x - 41 ) (x + 21)

To summarize, since -41 and 21 multiply to -861 and add up -20, you know that the following is true:

x² - 20x - 861 = (x - 41 ) (x + 21)
