What two numbers multiply to -576 and add up to 20?

Here we answer the question: "What two numbers multiply to -576 and add up to 20?"

The answer to your question is:

-16 and 36

Below we illustrate and prove that -16 and 36 multiply to -576 and add up to 20:

-16 × 36 = -576
-16 + 36 = 20

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

x² + 20x - 576 = 0

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

(x - 16 ) (x + 36)

To summarize, since -16 and 36 multiply to -576 and add up 20, you know that the following is true:

x² + 20x - 576 = (x - 16 ) (x + 36)
