What two numbers multiply to -458 and add up to 457?

Here we answer the question: "What two numbers multiply to -458 and add up to 457?"

The answer to your question is:

-1 and 458

Below we illustrate and prove that -1 and 458 multiply to -458 and add up to 457:

-1 × 458 = -458
-1 + 458 = 457

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

x² + 457x - 458 = 0

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

(x - 1 ) (x + 458)

To summarize, since -1 and 458 multiply to -458 and add up 457, you know that the following is true:

x² + 457x - 458 = (x - 1 ) (x + 458)
