What two numbers multiply to -648 and add up to -3?

Here we answer the question: "What two numbers multiply to -648 and add up to -3?"

The answer to your question is:

-27 and 24

Below we illustrate and prove that -27 and 24 multiply to -648 and add up to -3:

-27 × 24 = -648
-27 + 24 = -3

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

x² - 3x - 648 = 0

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

(x - 27 ) (x + 24)

To summarize, since -27 and 24 multiply to -648 and add up -3, you know that the following is true:

x² - 3x - 648 = (x - 27 ) (x + 24)
