What two numbers multiply to -728 and add up to 178?

Here we answer the question: "What two numbers multiply to -728 and add up to 178?"

The answer to your question is:

-4 and 182

Below we illustrate and prove that -4 and 182 multiply to -728 and add up to 178:

-4 × 182 = -728
-4 + 182 = 178

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

x² + 178x - 728 = 0

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

(x - 4 ) (x + 182)

To summarize, since -4 and 182 multiply to -728 and add up 178, you know that the following is true:

x² + 178x - 728 = (x - 4 ) (x + 182)
