What two numbers multiply to -972 and add up to 321?

Here we answer the question: "What two numbers multiply to -972 and add up to 321?"

The answer to your question is:

-3 and 324

Below we illustrate and prove that -3 and 324 multiply to -972 and add up to 321:

-3 × 324 = -972
-3 + 324 = 321

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

x² + 321x - 972 = 0

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

(x - 3 ) (x + 324)

To summarize, since -3 and 324 multiply to -972 and add up 321, you know that the following is true:

x² + 321x - 972 = (x - 3 ) (x + 324)
