What two numbers multiply to -496 and add up to -15?

Here we answer the question: "What two numbers multiply to -496 and add up to -15?"

The answer to your question is:

-31 and 16

Below we illustrate and prove that -31 and 16 multiply to -496 and add up to -15:

-31 × 16 = -496
-31 + 16 = -15

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

x² - 15x - 496 = 0

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

(x - 31 ) (x + 16)

To summarize, since -31 and 16 multiply to -496 and add up -15, you know that the following is true:

x² - 15x - 496 = (x - 31 ) (x + 16)
