What two numbers multiply to -254 and add up to 253?

Here we answer the question: "What two numbers multiply to -254 and add up to 253?"

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 253:

-1 × 254 = -254
-1 + 254 = 253

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

x² + 253x - 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 253, you know that the following is true:

x² + 253x - 254 = (x - 1 ) (x + 254)
