What two numbers multiply to -576 and add up to -55?

Here we answer the question: "What two numbers multiply to -576 and add up to -55?"

The answer to your question is:

-64 and 9

Below we illustrate and prove that -64 and 9 multiply to -576 and add up to -55:

-64 × 9 = -576
-64 + 9 = -55

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

x² - 55x - 576 = 0

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

(x - 64 ) (x + 9)

To summarize, since -64 and 9 multiply to -576 and add up -55, you know that the following is true:

x² - 55x - 576 = (x - 64 ) (x + 9)
