What two numbers multiply to -917 and add up to 916?

Here we answer the question: "What two numbers multiply to -917 and add up to 916?"

The answer to your question is:

-1 and 917

Below we illustrate and prove that -1 and 917 multiply to -917 and add up to 916:

-1 × 917 = -917
-1 + 917 = 916

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

x² + 916x - 917 = 0

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

(x - 1 ) (x + 917)

To summarize, since -1 and 917 multiply to -917 and add up 916, you know that the following is true:

x² + 916x - 917 = (x - 1 ) (x + 917)
