What two numbers multiply to -728 and add up to -2?

Here we answer the question: "What two numbers multiply to -728 and add up to -2?"

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 -2:

-28 × 26 = -728
-28 + 26 = -2

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

x² - 2x - 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 -2, you know that the following is true:

x² - 2x - 728 = (x - 28 ) (x + 26)
