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:

-4 and 144

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

-4 × 144 = -576
-4 + 144 = 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 - 4 ) (x + 144)

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

x² + 140x - 576 = (x - 4 ) (x + 144)
