What two numbers multiply to -855 and add up to 854?

Here we answer the question: "What two numbers multiply to -855 and add up to 854?"

The answer to your question is:

-1 and 855

Below we illustrate and prove that -1 and 855 multiply to -855 and add up to 854:

-1 × 855 = -855
-1 + 855 = 854

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

x² + 854x - 855 = 0

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

(x - 1 ) (x + 855)

To summarize, since -1 and 855 multiply to -855 and add up 854, you know that the following is true:

x² + 854x - 855 = (x - 1 ) (x + 855)
