What two numbers multiply to 816 and add up to 410?

Here we answer the question: "What two numbers multiply to 816 and add up to 410?"

The answer to your question is:

2 and 408

Below we illustrate and prove that 2 and 408 multiply to 816 and add up to 410:

2 × 408 = 816
2 + 408 = 410

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

x² + 410x + 816 = 0

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

(x + 2 ) (x + 408)

To summarize, since 2 and 408 multiply to 816 and add up 410, you know that the following is true:

x² + 410x + 816 = (x + 2 ) (x + 408)
