What two numbers multiply to -728 and add up to -43?

Here we answer the question: "What two numbers multiply to -728 and add up to -43?"

The answer to your question is:

-56 and 13

Below we illustrate and prove that -56 and 13 multiply to -728 and add up to -43:

-56 × 13 = -728
-56 + 13 = -43

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

x² - 43x - 728 = 0

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

(x - 56 ) (x + 13)

To summarize, since -56 and 13 multiply to -728 and add up -43, you know that the following is true:

x² - 43x - 728 = (x - 56 ) (x + 13)
