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:

-90 and -11

Below we illustrate and prove that -90 and -11 multiply to 990 and add up to -101:

-90 × -11 = 990
-90 + -11 = -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 - 90 ) (x - 11)

To summarize, since -90 and -11 multiply to 990 and add up -101, you know that the following is true:

x² - 101x + 990 = (x - 90 ) (x - 11)
