What two numbers multiply to -916 and add up to 456?

Here we answer the question: "What two numbers multiply to -916 and add up to 456?"

The answer to your question is:

-2 and 458

Below we illustrate and prove that -2 and 458 multiply to -916 and add up to 456:

-2 × 458 = -916
-2 + 458 = 456

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

x² + 456x - 916 = 0

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

(x - 2 ) (x + 458)

To summarize, since -2 and 458 multiply to -916 and add up 456, you know that the following is true:

x² + 456x - 916 = (x - 2 ) (x + 458)
