What two numbers multiply to -720 and add up to 176?

Here we answer the question: "What two numbers multiply to -720 and add up to 176?"

The answer to your question is:

-4 and 180

Below we illustrate and prove that -4 and 180 multiply to -720 and add up to 176:

-4 × 180 = -720
-4 + 180 = 176

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

x² + 176x - 720 = 0

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

(x - 4 ) (x + 180)

To summarize, since -4 and 180 multiply to -720 and add up 176, you know that the following is true:

x² + 176x - 720 = (x - 4 ) (x + 180)
