What two numbers multiply to 400 and add up to 202?

Here we answer the question: "What two numbers multiply to 400 and add up to 202?"

The answer to your question is:

2 and 200

Below we illustrate and prove that 2 and 200 multiply to 400 and add up to 202:

2 × 200 = 400
2 + 200 = 202

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

x² + 202x + 400 = 0

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

(x + 2 ) (x + 200)

To summarize, since 2 and 200 multiply to 400 and add up 202, you know that the following is true:

x² + 202x + 400 = (x + 2 ) (x + 200)
