What two numbers multiply to 521 and add up to 522?

Here we answer the question: "What two numbers multiply to 521 and add up to 522?"

The answer to your question is:

1 and 521

Below we illustrate and prove that 1 and 521 multiply to 521 and add up to 522:

1 × 521 = 521
1 + 521 = 522

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

x² + 522x + 521 = 0

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

(x + 1 ) (x + 521)

To summarize, since 1 and 521 multiply to 521 and add up 522, you know that the following is true:

x² + 522x + 521 = (x + 1 ) (x + 521)
