What two numbers multiply to 216 and add up to 217?

Here we answer the question: "What two numbers multiply to 216 and add up to 217?"

The answer to your question is:

1 and 216

Below we illustrate and prove that 1 and 216 multiply to 216 and add up to 217:

1 × 216 = 216
1 + 216 = 217

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

x² + 217x + 216 = 0

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

(x + 1 ) (x + 216)

To summarize, since 1 and 216 multiply to 216 and add up 217, you know that the following is true:

x² + 217x + 216 = (x + 1 ) (x + 216)
