What two numbers multiply to -916 and add up to 915?

Here we answer the question: "What two numbers multiply to -916 and add up to 915?"

The answer to your question is:

-1 and 916

Below we illustrate and prove that -1 and 916 multiply to -916 and add up to 915:

-1 × 916 = -916
-1 + 916 = 915

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

x² + 915x - 916 = 0

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

(x - 1 ) (x + 916)

To summarize, since -1 and 916 multiply to -916 and add up 915, you know that the following is true:

x² + 915x - 916 = (x - 1 ) (x + 916)
