What two numbers multiply to -605 and add up to 604?

Here we answer the question: "What two numbers multiply to -605 and add up to 604?"

The answer to your question is:

-1 and 605

Below we illustrate and prove that -1 and 605 multiply to -605 and add up to 604:

-1 × 605 = -605
-1 + 605 = 604

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

x² + 604x - 605 = 0

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

(x - 1 ) (x + 605)

To summarize, since -1 and 605 multiply to -605 and add up 604, you know that the following is true:

x² + 604x - 605 = (x - 1 ) (x + 605)
