What two numbers multiply to 104 and add up to -105?

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

The answer to your question is:

-104 and -1

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

-104 × -1 = 104
-104 + -1 = -105

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

x² - 105x + 104 = 0

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

(x - 104 ) (x - 1)

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

x² - 105x + 104 = (x - 104 ) (x - 1)
