Here we answer the question: "What two numbers multiply to -280 and add up to 66?"

The answer to your question is:

-4 and 70


as proven here:

-4 x 70 = -280
-4 + (70) = 66

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

x2 + 66x - 280 = 0

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

(X - 4 ) (X + 70)

To summarize, since -4 and 70 multiply to -280 and add up 66, you know that the following is true:

x2 + 66x - 280 = (X - 4 ) (X + 70)
