What two numbers multiply to -560 and add up to 278?

Here we answer the question: "What two numbers multiply to -560 and add up to 278?"

The answer to your question is:

-2 and 280

Below we illustrate and prove that -2 and 280 multiply to -560 and add up to 278:

-2 × 280 = -560
-2 + 280 = 278

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

x² + 278x - 560 = 0

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

(x - 2 ) (x + 280)

To summarize, since -2 and 280 multiply to -560 and add up 278, you know that the following is true:

x² + 278x - 560 = (x - 2 ) (x + 280)
