What two numbers multiply to -999 and add up to 330?

Here we answer the question: "What two numbers multiply to -999 and add up to 330?"

The answer to your question is:

-3 and 333

Below we illustrate and prove that -3 and 333 multiply to -999 and add up to 330:

-3 × 333 = -999
-3 + 333 = 330

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

x² + 330x - 999 = 0

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

(x - 3 ) (x + 333)

To summarize, since -3 and 333 multiply to -999 and add up 330, you know that the following is true:

x² + 330x - 999 = (x - 3 ) (x + 333)
