What two numbers multiply to 721 and add up to 722?

Here we answer the question: "What two numbers multiply to 721 and add up to 722?"

The answer to your question is:

1 and 721

Below we illustrate and prove that 1 and 721 multiply to 721 and add up to 722:

1 × 721 = 721
1 + 721 = 722

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

x² + 722x + 721 = 0

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

(x + 1 ) (x + 721)

To summarize, since 1 and 721 multiply to 721 and add up 722, you know that the following is true:

x² + 722x + 721 = (x + 1 ) (x + 721)
