What two numbers multiply to 720 and add up to -82?

Here we answer the question: "What two numbers multiply to 720 and add up to -82?"

The answer to your question is:

-72 and -10

Below we illustrate and prove that -72 and -10 multiply to 720 and add up to -82:

-72 × -10 = 720
-72 + -10 = -82

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

x² - 82x + 720 = 0

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

(x - 72 ) (x - 10)

To summarize, since -72 and -10 multiply to 720 and add up -82, you know that the following is true:

x² - 82x + 720 = (x - 72 ) (x - 10)
