What two numbers multiply to -255 and add up to 2?




Here we answer the question: "What two numbers multiply to -255 and add up to 2?"

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 2:

-15 × 17 = -255
-15 + 17 = 2

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

x2 + 2x - 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 2, you know that the following is true:

x2 + 2x - 255 = (x - 15 ) (x + 17)
