Here we answer the question: "What two numbers multiply to -512 and add up to -254?"
The answer to your question is:
-256 and 2
Below we illustrate and prove that -256 and 2 multiply to -512 and add up to -254:
-256 × 2 = -512
-256 + 2 = -254
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 254x - 512 = 0
If so, the solution to factor the quadratic equation above is:
(x - 256 ) (x + 2)
To summarize, since -256 and 2 multiply to -512 and add up -254, you know that the following is true:
x2 - 254x - 512 = (x - 256 ) (x + 2)
