What two numbers multiply to -576 and add up to -140?

Here we answer the question: "What two numbers multiply to -576 and add up to -140?"

The answer to your question is:

-144 and 4

Below we illustrate and prove that -144 and 4 multiply to -576 and add up to -140:

-144 × 4 = -576
-144 + 4 = -140

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

x² - 140x - 576 = 0

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

(x - 144 ) (x + 4)

To summarize, since -144 and 4 multiply to -576 and add up -140, you know that the following is true:

x² - 140x - 576 = (x - 144 ) (x + 4)
