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:

-128 and -2

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

-128 × -2 = 256
-128 + -2 = -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 - 128 ) (x - 2)

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

x² - 130x + 256 = (x - 128 ) (x - 2)
