What two numbers multiply to 720 and add up to 72?

Here we answer the question: "What two numbers multiply to 720 and add up to 72?"

The answer to your question is:

12 and 60

Below we illustrate and prove that 12 and 60 multiply to 720 and add up to 72:

12 × 60 = 720
12 + 60 = 72

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

x² + 72x + 720 = 0

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

(x + 12 ) (x + 60)

To summarize, since 12 and 60 multiply to 720 and add up 72, you know that the following is true:

x² + 72x + 720 = (x + 12 ) (x + 60)
