What two numbers multiply to -648 and add up to 322?

Here we answer the question: "What two numbers multiply to -648 and add up to 322?"

The answer to your question is:

-2 and 324

Below we illustrate and prove that -2 and 324 multiply to -648 and add up to 322:

-2 × 324 = -648
-2 + 324 = 322

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

x² + 322x - 648 = 0

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

(x - 2 ) (x + 324)

To summarize, since -2 and 324 multiply to -648 and add up 322, you know that the following is true:

x² + 322x - 648 = (x - 2 ) (x + 324)
