Here we answer the question: "What two numbers multiply to 819 and add up to 820?"

The answer to your question is:

1 and 819

Below we illustrate and prove that 1 and 819 multiply to 819 and add up to 820:

1 × 819 = 819
1 + 819 = 820

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

x² + 820x + 819 = 0

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

(x + 1 ) (x + 819)

To summarize, since 1 and 819 multiply to 819 and add up 820, you know that the following is true:

x² + 820x + 819 = (x + 1 ) (x + 819)
