What two numbers multiply to -172 and add up to 171?

Here we answer the question: "What two numbers multiply to -172 and add up to 171?"

The answer to your question is:

-1 and 172

Below we illustrate and prove that -1 and 172 multiply to -172 and add up to 171:

-1 × 172 = -172
-1 + 172 = 171

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

x² + 171x - 172 = 0

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

(x - 1 ) (x + 172)

To summarize, since -1 and 172 multiply to -172 and add up 171, you know that the following is true:

x² + 171x - 172 = (x - 1 ) (x + 172)
