What two numbers multiply to -412 and add up to 411?

Here we answer the question: "What two numbers multiply to -412 and add up to 411?"

The answer to your question is:

-1 and 412

Below we illustrate and prove that -1 and 412 multiply to -412 and add up to 411:

-1 × 412 = -412
-1 + 412 = 411

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

x² + 411x - 412 = 0

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

(x - 1 ) (x + 412)

To summarize, since -1 and 412 multiply to -412 and add up 411, you know that the following is true:

x² + 411x - 412 = (x - 1 ) (x + 412)
