What two numbers multiply to -609 and add up to 608?

Here we answer the question: "What two numbers multiply to -609 and add up to 608?"

The answer to your question is:

-1 and 609

Below we illustrate and prove that -1 and 609 multiply to -609 and add up to 608:

-1 × 609 = -609
-1 + 609 = 608

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

x² + 608x - 609 = 0

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

(x - 1 ) (x + 609)

To summarize, since -1 and 609 multiply to -609 and add up 608, you know that the following is true:

x² + 608x - 609 = (x - 1 ) (x + 609)
