What two numbers multiply to -663 and add up to 662?

Here we answer the question: "What two numbers multiply to -663 and add up to 662?"

The answer to your question is:

-1 and 663

Below we illustrate and prove that -1 and 663 multiply to -663 and add up to 662:

-1 × 663 = -663
-1 + 663 = 662

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

x² + 662x - 663 = 0

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

(x - 1 ) (x + 663)

To summarize, since -1 and 663 multiply to -663 and add up 662, you know that the following is true:

x² + 662x - 663 = (x - 1 ) (x + 663)
