What two numbers multiply to -579 and add up to 578?

Here we answer the question: "What two numbers multiply to -579 and add up to 578?"

The answer to your question is:

-1 and 579

Below we illustrate and prove that -1 and 579 multiply to -579 and add up to 578:

-1 × 579 = -579
-1 + 579 = 578

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

x² + 578x - 579 = 0

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

(x - 1 ) (x + 579)

To summarize, since -1 and 579 multiply to -579 and add up 578, you know that the following is true:

x² + 578x - 579 = (x - 1 ) (x + 579)
