What two numbers multiply to -660 and add up to 328?

Here we answer the question: "What two numbers multiply to -660 and add up to 328?"

The answer to your question is:

-2 and 330

Below we illustrate and prove that -2 and 330 multiply to -660 and add up to 328:

-2 × 330 = -660
-2 + 330 = 328

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

x² + 328x - 660 = 0

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

(x - 2 ) (x + 330)

To summarize, since -2 and 330 multiply to -660 and add up 328, you know that the following is true:

x² + 328x - 660 = (x - 2 ) (x + 330)
