What two numbers multiply to 728 and add up to 69?

Here we answer the question: "What two numbers multiply to 728 and add up to 69?"

The answer to your question is:

13 and 56

Below we illustrate and prove that 13 and 56 multiply to 728 and add up to 69:

13 × 56 = 728
13 + 56 = 69

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

x² + 69x + 728 = 0

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

(x + 13 ) (x + 56)

To summarize, since 13 and 56 multiply to 728 and add up 69, you know that the following is true:

x² + 69x + 728 = (x + 13 ) (x + 56)
