What two numbers multiply to -972 and add up to 239?

Here we answer the question: "What two numbers multiply to -972 and add up to 239?"

The answer to your question is:

-4 and 243

Below we illustrate and prove that -4 and 243 multiply to -972 and add up to 239:

-4 × 243 = -972
-4 + 243 = 239

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

x² + 239x - 972 = 0

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

(x - 4 ) (x + 243)

To summarize, since -4 and 243 multiply to -972 and add up 239, you know that the following is true:

x² + 239x - 972 = (x - 4 ) (x + 243)
