What two numbers multiply to 255 and add up to -32?

Here we answer the question: "What two numbers multiply to 255 and add up to -32?"

The answer to your question is:

-17 and -15

Below we illustrate and prove that -17 and -15 multiply to 255 and add up to -32:

-17 × -15 = 255
-17 + -15 = -32

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

x² - 32x + 255 = 0

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

(x - 17 ) (x - 15)

To summarize, since -17 and -15 multiply to 255 and add up -32, you know that the following is true:

x² - 32x + 255 = (x - 17 ) (x - 15)
