What two numbers multiply to -836 and add up to 416?

Here we answer the question: "What two numbers multiply to -836 and add up to 416?"

The answer to your question is:

-2 and 418

Below we illustrate and prove that -2 and 418 multiply to -836 and add up to 416:

-2 × 418 = -836
-2 + 418 = 416

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

x² + 416x - 836 = 0

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

(x - 2 ) (x + 418)

To summarize, since -2 and 418 multiply to -836 and add up 416, you know that the following is true:

x² + 416x - 836 = (x - 2 ) (x + 418)
