What two numbers multiply to -872 and add up to 434?

Here we answer the question: "What two numbers multiply to -872 and add up to 434?"

The answer to your question is:

-2 and 436

Below we illustrate and prove that -2 and 436 multiply to -872 and add up to 434:

-2 × 436 = -872
-2 + 436 = 434

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

x² + 434x - 872 = 0

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

(x - 2 ) (x + 436)

To summarize, since -2 and 436 multiply to -872 and add up 434, you know that the following is true:

x² + 434x - 872 = (x - 2 ) (x + 436)
