What two numbers multiply to -162 and add up to -21?

Here we answer the question: "What two numbers multiply to -162 and add up to -21?"

The answer to your question is:

-27 and 6

Below we illustrate and prove that -27 and 6 multiply to -162 and add up to -21:

-27 × 6 = -162
-27 + 6 = -21

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

x² - 21x - 162 = 0

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

(x - 27 ) (x + 6)

To summarize, since -27 and 6 multiply to -162 and add up -21, you know that the following is true:

x² - 21x - 162 = (x - 27 ) (x + 6)
