What two numbers multiply to -504 and add up to -30?

Here we answer the question: "What two numbers multiply to -504 and add up to -30?"

The answer to your question is:

-42 and 12

Below we illustrate and prove that -42 and 12 multiply to -504 and add up to -30:

-42 × 12 = -504
-42 + 12 = -30

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

x² - 30x - 504 = 0

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

(x - 42 ) (x + 12)

To summarize, since -42 and 12 multiply to -504 and add up -30, you know that the following is true:

x² - 30x - 504 = (x - 42 ) (x + 12)
