What two numbers multiply to -513 and add up to 512?




Here we answer the question: "What two numbers multiply to -513 and add up to 512?"

The answer to your question is:

-1 and 513


Below we illustrate and prove that -1 and 513 multiply to -513 and add up to 512:

-1 × 513 = -513
-1 + 513 = 512

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

x2 + 512x - 513 = 0

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

(x - 1 ) (x + 513)

To summarize, since -1 and 513 multiply to -513 and add up 512, you know that the following is true:

x2 + 512x - 513 = (x - 1 ) (x + 513)
