What two numbers multiply to -834 and add up to 415?

Here we answer the question: "What two numbers multiply to -834 and add up to 415?"

The answer to your question is:

-2 and 417

Below we illustrate and prove that -2 and 417 multiply to -834 and add up to 415:

-2 × 417 = -834
-2 + 417 = 415

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

x² + 415x - 834 = 0

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

(x - 2 ) (x + 417)

To summarize, since -2 and 417 multiply to -834 and add up 415, you know that the following is true:

x² + 415x - 834 = (x - 2 ) (x + 417)
