What two numbers multiply to 870 and add up to -871?

Here we answer the question: "What two numbers multiply to 870 and add up to -871?"

The answer to your question is:

-870 and -1

Below we illustrate and prove that -870 and -1 multiply to 870 and add up to -871:

-870 × -1 = 870
-870 + -1 = -871

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

x² - 871x + 870 = 0

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

(x - 870 ) (x - 1)

To summarize, since -870 and -1 multiply to 870 and add up -871, you know that the following is true:

x² - 871x + 870 = (x - 870 ) (x - 1)
