What two numbers multiply to 421 and add up to 422?

Here we answer the question: "What two numbers multiply to 421 and add up to 422?"

The answer to your question is:

1 and 421

Below we illustrate and prove that 1 and 421 multiply to 421 and add up to 422:

1 × 421 = 421
1 + 421 = 422

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

x² + 422x + 421 = 0

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

(x + 1 ) (x + 421)

To summarize, since 1 and 421 multiply to 421 and add up 422, you know that the following is true:

x² + 422x + 421 = (x + 1 ) (x + 421)
