What two numbers multiply to -189 and add up to -20?

Here we answer the question: "What two numbers multiply to -189 and add up to -20?"

The answer to your question is:

-27 and 7

Below we illustrate and prove that -27 and 7 multiply to -189 and add up to -20:

-27 × 7 = -189
-27 + 7 = -20

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

x² - 20x - 189 = 0

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

(x - 27 ) (x + 7)

To summarize, since -27 and 7 multiply to -189 and add up -20, you know that the following is true:

x² - 20x - 189 = (x - 27 ) (x + 7)
