What two numbers multiply to 422 and add up to 423?

Here we answer the question: "What two numbers multiply to 422 and add up to 423?"

The answer to your question is:

1 and 422

Below we illustrate and prove that 1 and 422 multiply to 422 and add up to 423:

1 × 422 = 422
1 + 422 = 423

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

x² + 423x + 422 = 0

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

(x + 1 ) (x + 422)

To summarize, since 1 and 422 multiply to 422 and add up 423, you know that the following is true:

x² + 423x + 422 = (x + 1 ) (x + 422)
