What two numbers multiply to 648 and add up to 219?

Here we answer the question: "What two numbers multiply to 648 and add up to 219?"

The answer to your question is:

3 and 216

Below we illustrate and prove that 3 and 216 multiply to 648 and add up to 219:

3 × 216 = 648
3 + 216 = 219

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

x² + 219x + 648 = 0

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

(x + 3 ) (x + 216)

To summarize, since 3 and 216 multiply to 648 and add up 219, you know that the following is true:

x² + 219x + 648 = (x + 3 ) (x + 216)
