What two numbers multiply to -768 and add up to -253?

Here we answer the question: "What two numbers multiply to -768 and add up to -253?"

The answer to your question is:

-256 and 3

Below we illustrate and prove that -256 and 3 multiply to -768 and add up to -253:

-256 × 3 = -768
-256 + 3 = -253

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

x² - 253x - 768 = 0

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

(x - 256 ) (x + 3)

To summarize, since -256 and 3 multiply to -768 and add up -253, you know that the following is true:

x² - 253x - 768 = (x - 256 ) (x + 3)
