What two numbers multiply to 728 and add up to -99?

Here we answer the question: "What two numbers multiply to 728 and add up to -99?"

The answer to your question is:

-91 and -8

Below we illustrate and prove that -91 and -8 multiply to 728 and add up to -99:

-91 × -8 = 728
-91 + -8 = -99

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

x² - 99x + 728 = 0

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

(x - 91 ) (x - 8)

To summarize, since -91 and -8 multiply to 728 and add up -99, you know that the following is true:

x² - 99x + 728 = (x - 91 ) (x - 8)
