Here we answer the question: "What two numbers multiply to -308 and add up to 17?"
The answer to your question is:
-11 and 28
Below we illustrate and prove that -11 and 28 multiply to -308 and add up to 17:
-11 × 28 = -308
-11 + 28 = 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 - 11 ) (x + 28)
To summarize, since -11 and 28 multiply to -308 and add up 17, you know that the following is true:
x2 + 17x - 308 = (x - 11 ) (x + 28)
