What two numbers multiply to 728 and add up to -54?

Here we answer the question: "What two numbers multiply to 728 and add up to -54?"

The answer to your question is:

-28 and -26

Below we illustrate and prove that -28 and -26 multiply to 728 and add up to -54:

-28 × -26 = 728
-28 + -26 = -54

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

x² - 54x + 728 = 0

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

(x - 28 ) (x - 26)

To summarize, since -28 and -26 multiply to 728 and add up -54, you know that the following is true:

x² - 54x + 728 = (x - 28 ) (x - 26)
