What two numbers multiply to -850 and add up to 423?

Here we answer the question: "What two numbers multiply to -850 and add up to 423?"

The answer to your question is:

-2 and 425

Below we illustrate and prove that -2 and 425 multiply to -850 and add up to 423:

-2 × 425 = -850
-2 + 425 = 423

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

x² + 423x - 850 = 0

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

(x - 2 ) (x + 425)

To summarize, since -2 and 425 multiply to -850 and add up 423, you know that the following is true:

x² + 423x - 850 = (x - 2 ) (x + 425)
