What two numbers multiply to -413 and add up to 412?

Here we answer the question: "What two numbers multiply to -413 and add up to 412?"

The answer to your question is:

-1 and 413

Below we illustrate and prove that -1 and 413 multiply to -413 and add up to 412:

-1 × 413 = -413
-1 + 413 = 412

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

x² + 412x - 413 = 0

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

(x - 1 ) (x + 413)

To summarize, since -1 and 413 multiply to -413 and add up 412, you know that the following is true:

x² + 412x - 413 = (x - 1 ) (x + 413)
