Here we answer the question: "What two numbers multiply to 396 and add up to 72?"

The answer to your question is:

6 and 66


Below we illustrate and prove that 6 and 66 multiply to 396 and add up to 72:

6 × 66 = 396
6 + 66 = 72

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

x2 + 72x + 396 = 0

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

(x + 6 ) (x + 66)

To summarize, since 6 and 66 multiply to 396 and add up 72, you know that the following is true:

x2 + 72x + 396 = (x + 6 ) (x + 66)
