What two numbers multiply to 215 and add up to 216?

Here we answer the question: "What two numbers multiply to 215 and add up to 216?"

The answer to your question is:

1 and 215

Below we illustrate and prove that 1 and 215 multiply to 215 and add up to 216:

1 × 215 = 215
1 + 215 = 216

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

x² + 216x + 215 = 0

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

(x + 1 ) (x + 215)

To summarize, since 1 and 215 multiply to 215 and add up 216, you know that the following is true:

x² + 216x + 215 = (x + 1 ) (x + 215)
