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

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

The answer to your question is:

-171 and -1

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

-171 × -1 = 171
-171 + -1 = -172

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

x² - 172x + 171 = 0

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

(x - 171 ) (x - 1)

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

x² - 172x + 171 = (x - 171 ) (x - 1)
