What two numbers multiply to 890 and add up to -891?

Here we answer the question: "What two numbers multiply to 890 and add up to -891?"

The answer to your question is:

-890 and -1

Below we illustrate and prove that -890 and -1 multiply to 890 and add up to -891:

-890 × -1 = 890
-890 + -1 = -891

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

x² - 891x + 890 = 0

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

(x - 890 ) (x - 1)

To summarize, since -890 and -1 multiply to 890 and add up -891, you know that the following is true:

x² - 891x + 890 = (x - 890 ) (x - 1)
