What two numbers multiply to -848 and add up to 422?

Here we answer the question: "What two numbers multiply to -848 and add up to 422?"

The answer to your question is:

-2 and 424

Below we illustrate and prove that -2 and 424 multiply to -848 and add up to 422:

-2 × 424 = -848
-2 + 424 = 422

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

x² + 422x - 848 = 0

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

(x - 2 ) (x + 424)

To summarize, since -2 and 424 multiply to -848 and add up 422, you know that the following is true:

x² + 422x - 848 = (x - 2 ) (x + 424)
