What two numbers multiply to -654 and add up to 653?

Here we answer the question: "What two numbers multiply to -654 and add up to 653?"

The answer to your question is:

-1 and 654

Below we illustrate and prove that -1 and 654 multiply to -654 and add up to 653:

-1 × 654 = -654
-1 + 654 = 653

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

x² + 653x - 654 = 0

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

(x - 1 ) (x + 654)

To summarize, since -1 and 654 multiply to -654 and add up 653, you know that the following is true:

x² + 653x - 654 = (x - 1 ) (x + 654)
