What two numbers multiply to 108 and add up to 109?

Here we answer the question: "What two numbers multiply to 108 and add up to 109?"

The answer to your question is:

1 and 108

Below we illustrate and prove that 1 and 108 multiply to 108 and add up to 109:

1 × 108 = 108
1 + 108 = 109

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

x² + 109x + 108 = 0

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

(x + 1 ) (x + 108)

To summarize, since 1 and 108 multiply to 108 and add up 109, you know that the following is true:

x² + 109x + 108 = (x + 1 ) (x + 108)
