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:

-2 and 201

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

-2 × 201 = -402
-2 + 201 = 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 - 2 ) (x + 201)

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

x² + 199x - 402 = (x - 2 ) (x + 201)
