What two numbers multiply to -877 and add up to 876?

Here we answer the question: "What two numbers multiply to -877 and add up to 876?"

The answer to your question is:

-1 and 877

Below we illustrate and prove that -1 and 877 multiply to -877 and add up to 876:

-1 × 877 = -877
-1 + 877 = 876

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

x² + 876x - 877 = 0

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

(x - 1 ) (x + 877)

To summarize, since -1 and 877 multiply to -877 and add up 876, you know that the following is true:

x² + 876x - 877 = (x - 1 ) (x + 877)
