What two numbers multiply to 798 and add up to 401?

Here we answer the question: "What two numbers multiply to 798 and add up to 401?"

The answer to your question is:

2 and 399

Below we illustrate and prove that 2 and 399 multiply to 798 and add up to 401:

2 × 399 = 798
2 + 399 = 401

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

x² + 401x + 798 = 0

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

(x + 2 ) (x + 399)

To summarize, since 2 and 399 multiply to 798 and add up 401, you know that the following is true:

x² + 401x + 798 = (x + 2 ) (x + 399)
