What two numbers multiply to -918 and add up to 917?

Here we answer the question: "What two numbers multiply to -918 and add up to 917?"

The answer to your question is:

-1 and 918

Below we illustrate and prove that -1 and 918 multiply to -918 and add up to 917:

-1 × 918 = -918
-1 + 918 = 917

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

x² + 917x - 918 = 0

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

(x - 1 ) (x + 918)

To summarize, since -1 and 918 multiply to -918 and add up 917, you know that the following is true:

x² + 917x - 918 = (x - 1 ) (x + 918)
