What two numbers multiply to -663 and add up to 22?

Here we answer the question: "What two numbers multiply to -663 and add up to 22?"

The answer to your question is:

-17 and 39

Below we illustrate and prove that -17 and 39 multiply to -663 and add up to 22:

-17 × 39 = -663
-17 + 39 = 22

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

x² + 22x - 663 = 0

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

(x - 17 ) (x + 39)

To summarize, since -17 and 39 multiply to -663 and add up 22, you know that the following is true:

x² + 22x - 663 = (x - 17 ) (x + 39)
