What two numbers multiply to -496 and add up to 120?

Here we answer the question: "What two numbers multiply to -496 and add up to 120?"

The answer to your question is:

-4 and 124

Below we illustrate and prove that -4 and 124 multiply to -496 and add up to 120:

-4 × 124 = -496
-4 + 124 = 120

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

x² + 120x - 496 = 0

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

(x - 4 ) (x + 124)

To summarize, since -4 and 124 multiply to -496 and add up 120, you know that the following is true:

x² + 120x - 496 = (x - 4 ) (x + 124)
