What two numbers multiply to 679 and add up to -104?

Here we answer the question: "What two numbers multiply to 679 and add up to -104?"

The answer to your question is:

-97 and -7

Below we illustrate and prove that -97 and -7 multiply to 679 and add up to -104:

-97 × -7 = 679
-97 + -7 = -104

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

x² - 104x + 679 = 0

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

(x - 97 ) (x - 7)

To summarize, since -97 and -7 multiply to 679 and add up -104, you know that the following is true:

x² - 104x + 679 = (x - 97 ) (x - 7)
