What two numbers multiply to -56 and add up to 10?

Here we answer the question: "What two numbers multiply to -56 and add up to 10?"

The answer to your question is:

-4 and 14

Below we illustrate and prove that -4 and 14 multiply to -56 and add up to 10:

-4 × 14 = -56
-4 + 14 = 10

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

x² + 10x - 56 = 0

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

(x - 4 ) (x + 14)

To summarize, since -4 and 14 multiply to -56 and add up 10, you know that the following is true:

x² + 10x - 56 = (x - 4 ) (x + 14)
