What two numbers multiply to -610 and add up to 609?

Here we answer the question: "What two numbers multiply to -610 and add up to 609?"

The answer to your question is:

-1 and 610

Below we illustrate and prove that -1 and 610 multiply to -610 and add up to 609:

-1 × 610 = -610
-1 + 610 = 609

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

x² + 609x - 610 = 0

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

(x - 1 ) (x + 610)

To summarize, since -1 and 610 multiply to -610 and add up 609, you know that the following is true:

x² + 609x - 610 = (x - 1 ) (x + 610)
