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:

3 and 240

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

3 × 240 = 720
3 + 240 = 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 + 3 ) (x + 240)

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

x² + 243x + 720 = (x + 3 ) (x + 240)
