What two numbers multiply to -104 and add up to 103?

Here we answer the question: "What two numbers multiply to -104 and add up to 103?"

The answer to your question is:

-1 and 104

Below we illustrate and prove that -1 and 104 multiply to -104 and add up to 103:

-1 × 104 = -104
-1 + 104 = 103

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

x² + 103x - 104 = 0

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

(x - 1 ) (x + 104)

To summarize, since -1 and 104 multiply to -104 and add up 103, you know that the following is true:

x² + 103x - 104 = (x - 1 ) (x + 104)
