What two numbers multiply to -872 and add up to 101?

Here we answer the question: "What two numbers multiply to -872 and add up to 101?"

The answer to your question is:

-8 and 109

Below we illustrate and prove that -8 and 109 multiply to -872 and add up to 101:

-8 × 109 = -872
-8 + 109 = 101

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

x² + 101x - 872 = 0

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

(x - 8 ) (x + 109)

To summarize, since -8 and 109 multiply to -872 and add up 101, you know that the following is true:

x² + 101x - 872 = (x - 8 ) (x + 109)
