What two numbers multiply to -166 and add up to -81?

Here we answer the question: "What two numbers multiply to -166 and add up to -81?"

The answer to your question is:

-83 and 2

Below we illustrate and prove that -83 and 2 multiply to -166 and add up to -81:

-83 × 2 = -166
-83 + 2 = -81

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

x² - 81x - 166 = 0

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

(x - 83 ) (x + 2)

To summarize, since -83 and 2 multiply to -166 and add up -81, you know that the following is true:

x² - 81x - 166 = (x - 83 ) (x + 2)
