What two numbers multiply to 800 and add up to 108?

Here we answer the question: "What two numbers multiply to 800 and add up to 108?"

The answer to your question is:

8 and 100

Below we illustrate and prove that 8 and 100 multiply to 800 and add up to 108:

8 × 100 = 800
8 + 100 = 108

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

x² + 108x + 800 = 0

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

(x + 8 ) (x + 100)

To summarize, since 8 and 100 multiply to 800 and add up 108, you know that the following is true:

x² + 108x + 800 = (x + 8 ) (x + 100)
