What two numbers multiply to -104 and add up to -5?

Here we answer the question: "What two numbers multiply to -104 and add up to -5?"

The answer to your question is:

-13 and 8

Below we illustrate and prove that -13 and 8 multiply to -104 and add up to -5:

-13 × 8 = -104
-13 + 8 = -5

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

x² - 5x - 104 = 0

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

(x - 13 ) (x + 8)

To summarize, since -13 and 8 multiply to -104 and add up -5, you know that the following is true:

x² - 5x - 104 = (x - 13 ) (x + 8)
