What two numbers multiply to -330 and add up to 7?

Here we answer the question: "What two numbers multiply to -330 and add up to 7?"

The answer to your question is:

-15 and 22

Below we illustrate and prove that -15 and 22 multiply to -330 and add up to 7:

-15 × 22 = -330
-15 + 22 = 7

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

x² + 7x - 330 = 0

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

(x - 15 ) (x + 22)

To summarize, since -15 and 22 multiply to -330 and add up 7, you know that the following is true:

x² + 7x - 330 = (x - 15 ) (x + 22)
