What two numbers multiply to -448 and add up to 447?

Here we answer the question: "What two numbers multiply to -448 and add up to 447?"

The answer to your question is:

-1 and 448

Below we illustrate and prove that -1 and 448 multiply to -448 and add up to 447:

-1 × 448 = -448
-1 + 448 = 447

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

x² + 447x - 448 = 0

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

(x - 1 ) (x + 448)

To summarize, since -1 and 448 multiply to -448 and add up 447, you know that the following is true:

x² + 447x - 448 = (x - 1 ) (x + 448)
