What two numbers multiply to -831 and add up to 830?

Here we answer the question: "What two numbers multiply to -831 and add up to 830?"

The answer to your question is:

-1 and 831

Below we illustrate and prove that -1 and 831 multiply to -831 and add up to 830:

-1 × 831 = -831
-1 + 831 = 830

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

x² + 830x - 831 = 0

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

(x - 1 ) (x + 831)

To summarize, since -1 and 831 multiply to -831 and add up 830, you know that the following is true:

x² + 830x - 831 = (x - 1 ) (x + 831)
