Here we answer the question: "What two numbers multiply to -648 and add up to 63?"

The answer to your question is:

-9 and 72


Below we illustrate and prove that -9 and 72 multiply to -648 and add up to 63:

-9 × 72 = -648
-9 + 72 = 63

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

x2 + 63x - 648 = 0

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

(x - 9 ) (x + 72)

To summarize, since -9 and 72 multiply to -648 and add up 63, you know that the following is true:

x2 + 63x - 648 = (x - 9 ) (x + 72)
