What two numbers multiply to -576 and add up to -90?

Here we answer the question: "What two numbers multiply to -576 and add up to -90?"

The answer to your question is:

-96 and 6

Below we illustrate and prove that -96 and 6 multiply to -576 and add up to -90:

-96 × 6 = -576
-96 + 6 = -90

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

x² - 90x - 576 = 0

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

(x - 96 ) (x + 6)

To summarize, since -96 and 6 multiply to -576 and add up -90, you know that the following is true:

x² - 90x - 576 = (x - 96 ) (x + 6)
