What two numbers multiply to 890 and add up to -99?

Here we answer the question: "What two numbers multiply to 890 and add up to -99?"

The answer to your question is:

-89 and -10

Below we illustrate and prove that -89 and -10 multiply to 890 and add up to -99:

-89 × -10 = 890
-89 + -10 = -99

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

x² - 99x + 890 = 0

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

(x - 89 ) (x - 10)

To summarize, since -89 and -10 multiply to 890 and add up -99, you know that the following is true:

x² - 99x + 890 = (x - 89 ) (x - 10)
