Here we answer the question: "What two numbers multiply to -55 and add up to -54?"

The answer to your question is:

-55 and 1

Below we illustrate and prove that -55 and 1 multiply to -55 and add up to -54:

-55 × 1 = -55
-55 + 1 = -54

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

x² - 54x - 55 = 0

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

(x - 55 ) (x + 1)

To summarize, since -55 and 1 multiply to -55 and add up -54, you know that the following is true:

x² - 54x - 55 = (x - 55 ) (x + 1)
