What two numbers multiply to 576 and add up to -73?

Here we answer the question: "What two numbers multiply to 576 and add up to -73?"

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 -73:

-64 × -9 = 576
-64 + -9 = -73

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

x² - 73x + 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 -73, you know that the following is true:

x² - 73x + 576 = (x - 64 ) (x - 9)
