What two numbers multiply to 256 and add up to 130?

Here we answer the question: "What two numbers multiply to 256 and add up to 130?"

The answer to your question is:

2 and 128

Below we illustrate and prove that 2 and 128 multiply to 256 and add up to 130:

2 × 128 = 256
2 + 128 = 130

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

x² + 130x + 256 = 0

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

(x + 2 ) (x + 128)

To summarize, since 2 and 128 multiply to 256 and add up 130, you know that the following is true:

x² + 130x + 256 = (x + 2 ) (x + 128)
