What two numbers multiply to -978 and add up to 323?

Here we answer the question: "What two numbers multiply to -978 and add up to 323?"

The answer to your question is:

-3 and 326

Below we illustrate and prove that -3 and 326 multiply to -978 and add up to 323:

-3 × 326 = -978
-3 + 326 = 323

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

x² + 323x - 978 = 0

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

(x - 3 ) (x + 326)

To summarize, since -3 and 326 multiply to -978 and add up 323, you know that the following is true:

x² + 323x - 978 = (x - 3 ) (x + 326)
