What two numbers multiply to -792 and add up to 91?

Here we answer the question: "What two numbers multiply to -792 and add up to 91?"

The answer to your question is:

-8 and 99

Below we illustrate and prove that -8 and 99 multiply to -792 and add up to 91:

-8 × 99 = -792
-8 + 99 = 91

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

x² + 91x - 792 = 0

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

(x - 8 ) (x + 99)

To summarize, since -8 and 99 multiply to -792 and add up 91, you know that the following is true:

x² + 91x - 792 = (x - 8 ) (x + 99)
