What two numbers multiply to 403 and add up to 404?

Here we answer the question: "What two numbers multiply to 403 and add up to 404?"

The answer to your question is:

1 and 403

Below we illustrate and prove that 1 and 403 multiply to 403 and add up to 404:

1 × 403 = 403
1 + 403 = 404

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

x² + 404x + 403 = 0

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

(x + 1 ) (x + 403)

To summarize, since 1 and 403 multiply to 403 and add up 404, you know that the following is true:

x² + 404x + 403 = (x + 1 ) (x + 403)
