What two numbers multiply to 217 and add up to 218?

Here we answer the question: "What two numbers multiply to 217 and add up to 218?"

The answer to your question is:

1 and 217

Below we illustrate and prove that 1 and 217 multiply to 217 and add up to 218:

1 × 217 = 217
1 + 217 = 218

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

x² + 218x + 217 = 0

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

(x + 1 ) (x + 217)

To summarize, since 1 and 217 multiply to 217 and add up 218, you know that the following is true:

x² + 218x + 217 = (x + 1 ) (x + 217)
