What two numbers multiply to -512 and add up to -16?

Here we answer the question: "What two numbers multiply to -512 and add up to -16?"

The answer to your question is:

-32 and 16

Below we illustrate and prove that -32 and 16 multiply to -512 and add up to -16:

-32 × 16 = -512
-32 + 16 = -16

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

x² - 16x - 512 = 0

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

(x - 32 ) (x + 16)

To summarize, since -32 and 16 multiply to -512 and add up -16, you know that the following is true:

x² - 16x - 512 = (x - 32 ) (x + 16)
