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:

-8 and 13

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

-8 × 13 = -104
-8 + 13 = 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 - 8 ) (x + 13)

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

x² + 5x - 104 = (x - 8 ) (x + 13)
