What two numbers multiply to -684 and add up to -20?

Here we answer the question: "What two numbers multiply to -684 and add up to -20?"

The answer to your question is:

-38 and 18

Below we illustrate and prove that -38 and 18 multiply to -684 and add up to -20:

-38 × 18 = -684
-38 + 18 = -20

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

x² - 20x - 684 = 0

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

(x - 38 ) (x + 18)

To summarize, since -38 and 18 multiply to -684 and add up -20, you know that the following is true:

x² - 20x - 684 = (x - 38 ) (x + 18)
