Here we answer the question: "What two numbers multiply to -240 and add up to -8?"

The answer to your question is:

12 and -20


as proven here:

12 x -20 = -240
12 + (-20) = -8

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

x2 - 8x - 240 = 0

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

(X + 12 ) (X - 20)

To summarize, since 12 and -20 multiply to -240 and add up -8, you know that the following is true:

x2 - 8x - 240 = (X + 12 ) (X - 20)
