What two numbers multiply to 398 and add up to 201?

Here we answer the question: "What two numbers multiply to 398 and add up to 201?"

The answer to your question is:

2 and 199

Below we illustrate and prove that 2 and 199 multiply to 398 and add up to 201:

2 × 199 = 398
2 + 199 = 201

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

x² + 201x + 398 = 0

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

(x + 2 ) (x + 199)

To summarize, since 2 and 199 multiply to 398 and add up 201, you know that the following is true:

x² + 201x + 398 = (x + 2 ) (x + 199)
