What two numbers multiply to -82 and add up to 81?

Here we answer the question: "What two numbers multiply to -82 and add up to 81?"

The answer to your question is:

-1 and 82

Below we illustrate and prove that -1 and 82 multiply to -82 and add up to 81:

-1 × 82 = -82
-1 + 82 = 81

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

x² + 81x - 82 = 0

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

(x - 1 ) (x + 82)

To summarize, since -1 and 82 multiply to -82 and add up 81, you know that the following is true:

x² + 81x - 82 = (x - 1 ) (x + 82)
