What two numbers multiply to 821 and add up to 822?

Here we answer the question: "What two numbers multiply to 821 and add up to 822?"

The answer to your question is:

1 and 821

Below we illustrate and prove that 1 and 821 multiply to 821 and add up to 822:

1 × 821 = 821
1 + 821 = 822

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

x² + 822x + 821 = 0

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

(x + 1 ) (x + 821)

To summarize, since 1 and 821 multiply to 821 and add up 822, you know that the following is true:

x² + 822x + 821 = (x + 1 ) (x + 821)
