What two numbers multiply to 424 and add up to 425?

Here we answer the question: "What two numbers multiply to 424 and add up to 425?"

The answer to your question is:

1 and 424

Below we illustrate and prove that 1 and 424 multiply to 424 and add up to 425:

1 × 424 = 424
1 + 424 = 425

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

x² + 425x + 424 = 0

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

(x + 1 ) (x + 424)

To summarize, since 1 and 424 multiply to 424 and add up 425, you know that the following is true:

x² + 425x + 424 = (x + 1 ) (x + 424)
