What two numbers multiply to -402 and add up to -199?

Here we answer the question: "What two numbers multiply to -402 and add up to -199?"

The answer to your question is:

-201 and 2

Below we illustrate and prove that -201 and 2 multiply to -402 and add up to -199:

-201 × 2 = -402
-201 + 2 = -199

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

x² - 199x - 402 = 0

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

(x - 201 ) (x + 2)

To summarize, since -201 and 2 multiply to -402 and add up -199, you know that the following is true:

x² - 199x - 402 = (x - 201 ) (x + 2)
