What two numbers multiply to 728 and add up to 729?

Here we answer the question: "What two numbers multiply to 728 and add up to 729?"

The answer to your question is:

1 and 728

Below we illustrate and prove that 1 and 728 multiply to 728 and add up to 729:

1 × 728 = 728
1 + 728 = 729

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

x² + 729x + 728 = 0

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

(x + 1 ) (x + 728)

To summarize, since 1 and 728 multiply to 728 and add up 729, you know that the following is true:

x² + 729x + 728 = (x + 1 ) (x + 728)
