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:

-7 and 27

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

-7 × 27 = -189
-7 + 27 = 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 - 7 ) (x + 27)

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

x² + 20x - 189 = (x - 7 ) (x + 27)
