Here we answer the question: "What two numbers multiply to -105 and add up to -104?"

The answer to your question is:

-105 and 1

Below we illustrate and prove that -105 and 1 multiply to -105 and add up to -104:

-105 × 1 = -105
-105 + 1 = -104

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

x² - 104x - 105 = 0

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

(x - 105 ) (x + 1)

To summarize, since -105 and 1 multiply to -105 and add up -104, you know that the following is true:

x² - 104x - 105 = (x - 105 ) (x + 1)
