What two numbers multiply to 254 and add up to 255?

Here we answer the question: "What two numbers multiply to 254 and add up to 255?"

The answer to your question is:

1 and 254

Below we illustrate and prove that 1 and 254 multiply to 254 and add up to 255:

1 × 254 = 254
1 + 254 = 255

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

x² + 255x + 254 = 0

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

(x + 1 ) (x + 254)

To summarize, since 1 and 254 multiply to 254 and add up 255, you know that the following is true:

x² + 255x + 254 = (x + 1 ) (x + 254)
