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:

-200 and -2

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

-200 × -2 = 400
-200 + -2 = -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 - 200 ) (x - 2)

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

x² - 202x + 400 = (x - 200 ) (x - 2)
