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:

-6 and 110

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

-6 × 110 = -660
-6 + 110 = 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 - 6 ) (x + 110)

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

x² + 104x - 660 = (x - 6 ) (x + 110)
