What two numbers multiply to -856 and add up to 855?

Here we answer the question: "What two numbers multiply to -856 and add up to 855?"

The answer to your question is:

-1 and 856

Below we illustrate and prove that -1 and 856 multiply to -856 and add up to 855:

-1 × 856 = -856
-1 + 856 = 855

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

x² + 855x - 856 = 0

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

(x - 1 ) (x + 856)

To summarize, since -1 and 856 multiply to -856 and add up 855, you know that the following is true:

x² + 855x - 856 = (x - 1 ) (x + 856)
