Here we answer the question: "What two numbers multiply to 872 and add up to -438?"

The answer to your question is:

-436 and -2

Below we illustrate and prove that -436 and -2 multiply to 872 and add up to -438:

-436 × -2 = 872
-436 + -2 = -438

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

x² - 438x + 872 = 0

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

(x - 436 ) (x - 2)

To summarize, since -436 and -2 multiply to 872 and add up -438, you know that the following is true:

x² - 438x + 872 = (x - 436 ) (x - 2)
