What two numbers multiply to 871 and add up to -872?

Here we answer the question: "What two numbers multiply to 871 and add up to -872?"

The answer to your question is:

-871 and -1

Below we illustrate and prove that -871 and -1 multiply to 871 and add up to -872:

-871 × -1 = 871
-871 + -1 = -872

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

x² - 872x + 871 = 0

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

(x - 871 ) (x - 1)

To summarize, since -871 and -1 multiply to 871 and add up -872, you know that the following is true:

x² - 872x + 871 = (x - 871 ) (x - 1)
