What two numbers multiply to -792 and add up to 79?

Here we answer the question: "What two numbers multiply to -792 and add up to 79?"

The answer to your question is:

-9 and 88

Below we illustrate and prove that -9 and 88 multiply to -792 and add up to 79:

-9 × 88 = -792
-9 + 88 = 79

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

x² + 79x - 792 = 0

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

(x - 9 ) (x + 88)

To summarize, since -9 and 88 multiply to -792 and add up 79, you know that the following is true:

x² + 79x - 792 = (x - 9 ) (x + 88)
