What two numbers multiply to 990 and add up to -119?

Here we answer the question: "What two numbers multiply to 990 and add up to -119?"

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 -119:

-110 × -9 = 990
-110 + -9 = -119

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

x² - 119x + 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 -119, you know that the following is true:

x² - 119x + 990 = (x - 110 ) (x - 9)
