Here we answer the question: "What two numbers multiply to -798 and add up to -17?"

The answer to your question is:

-38 and 21

Below we illustrate and prove that -38 and 21 multiply to -798 and add up to -17:

-38 × 21 = -798
-38 + 21 = -17

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

x² - 17x - 798 = 0

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

(x - 38 ) (x + 21)

To summarize, since -38 and 21 multiply to -798 and add up -17, you know that the following is true:

x² - 17x - 798 = (x - 38 ) (x + 21)
