What two numbers multiply to -329 and add up to 328?

Here we answer the question: "What two numbers multiply to -329 and add up to 328?"

The answer to your question is:

-1 and 329

Below we illustrate and prove that -1 and 329 multiply to -329 and add up to 328:

-1 × 329 = -329
-1 + 329 = 328

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

x² + 328x - 329 = 0

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

(x - 1 ) (x + 329)

To summarize, since -1 and 329 multiply to -329 and add up 328, you know that the following is true:

x² + 328x - 329 = (x - 1 ) (x + 329)
