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:

15 and 17

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

15 × 17 = 255
15 + 17 = 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 + 15 ) (x + 17)

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

x² + 32x + 255 = (x + 15 ) (x + 17)
