What two numbers multiply to -308 and add up to -17?

Here we answer the question: "What two numbers multiply to -308 and add up to -17?"

The answer to your question is:

-28 and 11

Below we illustrate and prove that -28 and 11 multiply to -308 and add up to -17:

-28 × 11 = -308
-28 + 11 = -17

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

x² - 17x - 308 = 0

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

(x - 28 ) (x + 11)

To summarize, since -28 and 11 multiply to -308 and add up -17, you know that the following is true:

x² - 17x - 308 = (x - 28 ) (x + 11)
