What two numbers multiply to 256 and add up to -32?

Here we answer the question: "What two numbers multiply to 256 and add up to -32?"

The answer to your question is:

-16 and -16

Below we illustrate and prove that -16 and -16 multiply to 256 and add up to -32:

-16 × -16 = 256
-16 + -16 = -32

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

x² - 32x + 256 = 0

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

(x - 16 ) (x - 16)

To summarize, since -16 and -16 multiply to 256 and add up -32, you know that the following is true:

x² - 32x + 256 = (x - 16 ) (x - 16)
