What two numbers multiply to -560 and add up to 8?

Here we answer the question: "What two numbers multiply to -560 and add up to 8?"

The answer to your question is:

-20 and 28

Below we illustrate and prove that -20 and 28 multiply to -560 and add up to 8:

-20 × 28 = -560
-20 + 28 = 8

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

x² + 8x - 560 = 0

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

(x - 20 ) (x + 28)

To summarize, since -20 and 28 multiply to -560 and add up 8, you know that the following is true:

x² + 8x - 560 = (x - 20 ) (x + 28)
