What two numbers multiply to 512 and add up to 258?

Here we answer the question: "What two numbers multiply to 512 and add up to 258?"

The answer to your question is:

2 and 256

Below we illustrate and prove that 2 and 256 multiply to 512 and add up to 258:

2 × 256 = 512
2 + 256 = 258

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

x² + 258x + 512 = 0

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

(x + 2 ) (x + 256)

To summarize, since 2 and 256 multiply to 512 and add up 258, you know that the following is true:

x² + 258x + 512 = (x + 2 ) (x + 256)
