What two numbers multiply to -990 and add up to -101?

Here we answer the question: "What two numbers multiply to -990 and add up to -101?"

The answer to your question is:

-110 and 9

Below we illustrate and prove that -110 and 9 multiply to -990 and add up to -101:

-110 × 9 = -990
-110 + 9 = -101

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

x² - 101x - 990 = 0

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

(x - 110 ) (x + 9)

To summarize, since -110 and 9 multiply to -990 and add up -101, you know that the following is true:

x² - 101x - 990 = (x - 110 ) (x + 9)
