What two numbers multiply to 809 and add up to 810?

Here we answer the question: "What two numbers multiply to 809 and add up to 810?"

The answer to your question is:

1 and 809

Below we illustrate and prove that 1 and 809 multiply to 809 and add up to 810:

1 × 809 = 809
1 + 809 = 810

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

x² + 810x + 809 = 0

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

(x + 1 ) (x + 809)

To summarize, since 1 and 809 multiply to 809 and add up 810, you know that the following is true:

x² + 810x + 809 = (x + 1 ) (x + 809)
