What two numbers multiply to -611 and add up to 610?

Here we answer the question: "What two numbers multiply to -611 and add up to 610?"

The answer to your question is:

-1 and 611

Below we illustrate and prove that -1 and 611 multiply to -611 and add up to 610:

-1 × 611 = -611
-1 + 611 = 610

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

x² + 610x - 611 = 0

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

(x - 1 ) (x + 611)

To summarize, since -1 and 611 multiply to -611 and add up 610, you know that the following is true:

x² + 610x - 611 = (x - 1 ) (x + 611)
