What two numbers multiply to 816 and add up to 817?

Here we answer the question: "What two numbers multiply to 816 and add up to 817?"

The answer to your question is:

1 and 816

Below we illustrate and prove that 1 and 816 multiply to 816 and add up to 817:

1 × 816 = 816
1 + 816 = 817

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

x² + 817x + 816 = 0

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

(x + 1 ) (x + 816)

To summarize, since 1 and 816 multiply to 816 and add up 817, you know that the following is true:

x² + 817x + 816 = (x + 1 ) (x + 816)
