What two numbers multiply to -660 and add up to -104?

Here we answer the question: "What two numbers multiply to -660 and add up to -104?"

The answer to your question is:

-110 and 6

Below we illustrate and prove that -110 and 6 multiply to -660 and add up to -104:

-110 × 6 = -660
-110 + 6 = -104

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

x² - 104x - 660 = 0

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

(x - 110 ) (x + 6)

To summarize, since -110 and 6 multiply to -660 and add up -104, you know that the following is true:

x² - 104x - 660 = (x - 110 ) (x + 6)
