What two numbers multiply to 330 and add up to -71?

Here we answer the question: "What two numbers multiply to 330 and add up to -71?"

The answer to your question is:

-66 and -5

Below we illustrate and prove that -66 and -5 multiply to 330 and add up to -71:

-66 × -5 = 330
-66 + -5 = -71

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

x² - 71x + 330 = 0

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

(x - 66 ) (x - 5)

To summarize, since -66 and -5 multiply to 330 and add up -71, you know that the following is true:

x² - 71x + 330 = (x - 66 ) (x - 5)
