What two numbers multiply to 720 and add up to 61?

Here we answer the question: "What two numbers multiply to 720 and add up to 61?"

The answer to your question is:

16 and 45

Below we illustrate and prove that 16 and 45 multiply to 720 and add up to 61:

16 × 45 = 720
16 + 45 = 61

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

x² + 61x + 720 = 0

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

(x + 16 ) (x + 45)

To summarize, since 16 and 45 multiply to 720 and add up 61, you know that the following is true:

x² + 61x + 720 = (x + 16 ) (x + 45)
