What two numbers multiply to -919 and add up to 918?

Here we answer the question: "What two numbers multiply to -919 and add up to 918?"

The answer to your question is:

-1 and 919

Below we illustrate and prove that -1 and 919 multiply to -919 and add up to 918:

-1 × 919 = -919
-1 + 919 = 918

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

x² + 918x - 919 = 0

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

(x - 1 ) (x + 919)

To summarize, since -1 and 919 multiply to -919 and add up 918, you know that the following is true:

x² + 918x - 919 = (x - 1 ) (x + 919)
