What two numbers multiply to -330 and add up to 61?

Here we answer the question: "What two numbers multiply to -330 and add up to 61?"

The answer to your question is:

-5 and 66

Below we illustrate and prove that -5 and 66 multiply to -330 and add up to 61:

-5 × 66 = -330
-5 + 66 = 61

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

x² + 61x - 330 = 0

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

(x - 5 ) (x + 66)

To summarize, since -5 and 66 multiply to -330 and add up 61, you know that the following is true:

x² + 61x - 330 = (x - 5 ) (x + 66)
