Here we answer the question: "What two numbers multiply to -56 and add up to -55?"

The answer to your question is:

-56 and 1

Below we illustrate and prove that -56 and 1 multiply to -56 and add up to -55:

-56 × 1 = -56
-56 + 1 = -55

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

x² - 55x - 56 = 0

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

(x - 56 ) (x + 1)

To summarize, since -56 and 1 multiply to -56 and add up -55, you know that the following is true:

x² - 55x - 56 = (x - 56 ) (x + 1)
