What two numbers multiply to 728 and add up to -111?

Here we answer the question: "What two numbers multiply to 728 and add up to -111?"

The answer to your question is:

-104 and -7

Below we illustrate and prove that -104 and -7 multiply to 728 and add up to -111:

-104 × -7 = 728
-104 + -7 = -111

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

x² - 111x + 728 = 0

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

(x - 104 ) (x - 7)

To summarize, since -104 and -7 multiply to 728 and add up -111, you know that the following is true:

x² - 111x + 728 = (x - 104 ) (x - 7)
