What two numbers multiply to -725 and add up to 140?

Here we answer the question: "What two numbers multiply to -725 and add up to 140?"

The answer to your question is:

-5 and 145

Below we illustrate and prove that -5 and 145 multiply to -725 and add up to 140:

-5 × 145 = -725
-5 + 145 = 140

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

x² + 140x - 725 = 0

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

(x - 5 ) (x + 145)

To summarize, since -5 and 145 multiply to -725 and add up 140, you know that the following is true:

x² + 140x - 725 = (x - 5 ) (x + 145)
