What two numbers multiply to -829 and add up to 828?

Here we answer the question: "What two numbers multiply to -829 and add up to 828?"

The answer to your question is:

-1 and 829

Below we illustrate and prove that -1 and 829 multiply to -829 and add up to 828:

-1 × 829 = -829
-1 + 829 = 828

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

x² + 828x - 829 = 0

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

(x - 1 ) (x + 829)

To summarize, since -1 and 829 multiply to -829 and add up 828, you know that the following is true:

x² + 828x - 829 = (x - 1 ) (x + 829)
