What two numbers multiply to -909 and add up to 908?

Here we answer the question: "What two numbers multiply to -909 and add up to 908?"

The answer to your question is:

-1 and 909

Below we illustrate and prove that -1 and 909 multiply to -909 and add up to 908:

-1 × 909 = -909
-1 + 909 = 908

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

x² + 908x - 909 = 0

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

(x - 1 ) (x + 909)

To summarize, since -1 and 909 multiply to -909 and add up 908, you know that the following is true:

x² + 908x - 909 = (x - 1 ) (x + 909)
