What two numbers multiply to 720 and add up to -243?

Here we answer the question: "What two numbers multiply to 720 and add up to -243?"

The answer to your question is:

-240 and -3

Below we illustrate and prove that -240 and -3 multiply to 720 and add up to -243:

-240 × -3 = 720
-240 + -3 = -243

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

x² - 243x + 720 = 0

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

(x - 240 ) (x - 3)

To summarize, since -240 and -3 multiply to 720 and add up -243, you know that the following is true:

x² - 243x + 720 = (x - 240 ) (x - 3)
