What two numbers multiply to -820 and add up to 201?

Here we answer the question: "What two numbers multiply to -820 and add up to 201?"

The answer to your question is:

-4 and 205

Below we illustrate and prove that -4 and 205 multiply to -820 and add up to 201:

-4 × 205 = -820
-4 + 205 = 201

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

x² + 201x - 820 = 0

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

(x - 4 ) (x + 205)

To summarize, since -4 and 205 multiply to -820 and add up 201, you know that the following is true:

x² + 201x - 820 = (x - 4 ) (x + 205)
