What two numbers multiply to -791 and add up to 790?

Here we answer the question: "What two numbers multiply to -791 and add up to 790?"

The answer to your question is:

-1 and 791

Below we illustrate and prove that -1 and 791 multiply to -791 and add up to 790:

-1 × 791 = -791
-1 + 791 = 790

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

x² + 790x - 791 = 0

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

(x - 1 ) (x + 791)

To summarize, since -1 and 791 multiply to -791 and add up 790, you know that the following is true:

x² + 790x - 791 = (x - 1 ) (x + 791)
