What two numbers multiply to -728 and add up to 727?

Here we answer the question: "What two numbers multiply to -728 and add up to 727?"

The answer to your question is:

-1 and 728

Below we illustrate and prove that -1 and 728 multiply to -728 and add up to 727:

-1 × 728 = -728
-1 + 728 = 727

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

x² + 727x - 728 = 0

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

(x - 1 ) (x + 728)

To summarize, since -1 and 728 multiply to -728 and add up 727, you know that the following is true:

x² + 727x - 728 = (x - 1 ) (x + 728)
