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:

-24 and 27

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

-24 × 27 = -648
-24 + 27 = 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 - 24 ) (x + 27)

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

x² + 3x - 648 = (x - 24 ) (x + 27)
