What two numbers multiply to -576 and add up to -64?

Here we answer the question: "What two numbers multiply to -576 and add up to -64?"

The answer to your question is:

-72 and 8

Below we illustrate and prove that -72 and 8 multiply to -576 and add up to -64:

-72 × 8 = -576
-72 + 8 = -64

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

x² - 64x - 576 = 0

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

(x - 72 ) (x + 8)

To summarize, since -72 and 8 multiply to -576 and add up -64, you know that the following is true:

x² - 64x - 576 = (x - 72 ) (x + 8)
