What two numbers multiply to 512 and add up to -132?

Here we answer the question: "What two numbers multiply to 512 and add up to -132?"

The answer to your question is:

-128 and -4

Below we illustrate and prove that -128 and -4 multiply to 512 and add up to -132:

-128 × -4 = 512
-128 + -4 = -132

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

x² - 132x + 512 = 0

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

(x - 128 ) (x - 4)

To summarize, since -128 and -4 multiply to 512 and add up -132, you know that the following is true:

x² - 132x + 512 = (x - 128 ) (x - 4)
