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:

5 and 66

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

5 × 66 = 330
5 + 66 = 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 + 5 ) (x + 66)

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

x² + 71x + 330 = (x + 5 ) (x + 66)
