Here we answer the question: "What two numbers multiply to -784 and add up to 42?"

The answer to your question is:

-14 and 56


Below we illustrate and prove that -14 and 56 multiply to -784 and add up to 42:

-14 × 56 = -784
-14 + 56 = 42

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

x2 + 42x - 784 = 0

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

(x - 14 ) (x + 56)

To summarize, since -14 and 56 multiply to -784 and add up 42, you know that the following is true:

x2 + 42x - 784 = (x - 14 ) (x + 56)
