What two numbers multiply to -989 and add up to -20?

Here we answer the question: "What two numbers multiply to -989 and add up to -20?"

The answer to your question is:

-43 and 23

Below we illustrate and prove that -43 and 23 multiply to -989 and add up to -20:

-43 × 23 = -989
-43 + 23 = -20

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

x² - 20x - 989 = 0

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

(x - 43 ) (x + 23)

To summarize, since -43 and 23 multiply to -989 and add up -20, you know that the following is true:

x² - 20x - 989 = (x - 43 ) (x + 23)
