What two numbers multiply to -457 and add up to 456?

Here we answer the question: "What two numbers multiply to -457 and add up to 456?"

The answer to your question is:

-1 and 457

Below we illustrate and prove that -1 and 457 multiply to -457 and add up to 456:

-1 × 457 = -457
-1 + 457 = 456

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

x² + 456x - 457 = 0

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

(x - 1 ) (x + 457)

To summarize, since -1 and 457 multiply to -457 and add up 456, you know that the following is true:

x² + 456x - 457 = (x - 1 ) (x + 457)
