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:

-6 and 27

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

-6 × 27 = -162
-6 + 27 = 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 - 6 ) (x + 27)

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

x² + 21x - 162 = (x - 6 ) (x + 27)
