What two numbers multiply to 512 and add up to -48?

Here we answer the question: "What two numbers multiply to 512 and add up to -48?"

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 -48:

-32 × -16 = 512
-32 + -16 = -48

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

x² - 48x + 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 -48, you know that the following is true:

x² - 48x + 512 = (x - 32 ) (x - 16)
