What two numbers multiply to -911 and add up to 910?

Here we answer the question: "What two numbers multiply to -911 and add up to 910?"

The answer to your question is:

-1 and 911

Below we illustrate and prove that -1 and 911 multiply to -911 and add up to 910:

-1 × 911 = -911
-1 + 911 = 910

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

x² + 910x - 911 = 0

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

(x - 1 ) (x + 911)

To summarize, since -1 and 911 multiply to -911 and add up 910, you know that the following is true:

x² + 910x - 911 = (x - 1 ) (x + 911)
