What two numbers multiply to -881 and add up to 880?

Here we answer the question: "What two numbers multiply to -881 and add up to 880?"

The answer to your question is:

-1 and 881

Below we illustrate and prove that -1 and 881 multiply to -881 and add up to 880:

-1 × 881 = -881
-1 + 881 = 880

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

x² + 880x - 881 = 0

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

(x - 1 ) (x + 881)

To summarize, since -1 and 881 multiply to -881 and add up 880, you know that the following is true:

x² + 880x - 881 = (x - 1 ) (x + 881)
