What two numbers multiply to -252 and add up to -81?

Here we answer the question: "What two numbers multiply to -252 and add up to -81?"

The answer to your question is:

-84 and 3

Below we illustrate and prove that -84 and 3 multiply to -252 and add up to -81:

-84 × 3 = -252
-84 + 3 = -81

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

x² - 81x - 252 = 0

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

(x - 84 ) (x + 3)

To summarize, since -84 and 3 multiply to -252 and add up -81, you know that the following is true:

x² - 81x - 252 = (x - 84 ) (x + 3)
