What two numbers multiply to -405 and add up to -132?

Here we answer the question: "What two numbers multiply to -405 and add up to -132?"

The answer to your question is:

-135 and 3

Below we illustrate and prove that -135 and 3 multiply to -405 and add up to -132:

-135 × 3 = -405
-135 + 3 = -132

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

x² - 132x - 405 = 0

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

(x - 135 ) (x + 3)

To summarize, since -135 and 3 multiply to -405 and add up -132, you know that the following is true:

x² - 132x - 405 = (x - 135 ) (x + 3)
