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:

4 and 128

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

4 × 128 = 512
4 + 128 = 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 + 4 ) (x + 128)

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

x² + 132x + 512 = (x + 4 ) (x + 128)
