What two numbers multiply to -728 and add up to 97?

Here we answer the question: "What two numbers multiply to -728 and add up to 97?"

The answer to your question is:

-7 and 104

Below we illustrate and prove that -7 and 104 multiply to -728 and add up to 97:

-7 × 104 = -728
-7 + 104 = 97

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

x² + 97x - 728 = 0

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

(x - 7 ) (x + 104)

To summarize, since -7 and 104 multiply to -728 and add up 97, you know that the following is true:

x² + 97x - 728 = (x - 7 ) (x + 104)
