What two numbers multiply to -449 and add up to 448?

Here we answer the question: "What two numbers multiply to -449 and add up to 448?"

The answer to your question is:

-1 and 449

Below we illustrate and prove that -1 and 449 multiply to -449 and add up to 448:

-1 × 449 = -449
-1 + 449 = 448

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

x² + 448x - 449 = 0

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

(x - 1 ) (x + 449)

To summarize, since -1 and 449 multiply to -449 and add up 448, you know that the following is true:

x² + 448x - 449 = (x - 1 ) (x + 449)
