What two numbers multiply to 820 and add up to 412?

Here we answer the question: "What two numbers multiply to 820 and add up to 412?"

The answer to your question is:

2 and 410

Below we illustrate and prove that 2 and 410 multiply to 820 and add up to 412:

2 × 410 = 820
2 + 410 = 412

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

x² + 412x + 820 = 0

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

(x + 2 ) (x + 410)

To summarize, since 2 and 410 multiply to 820 and add up 412, you know that the following is true:

x² + 412x + 820 = (x + 2 ) (x + 410)
