What two numbers multiply to -855 and add up to 166?

Here we answer the question: "What two numbers multiply to -855 and add up to 166?"

The answer to your question is:

-5 and 171

Below we illustrate and prove that -5 and 171 multiply to -855 and add up to 166:

-5 × 171 = -855
-5 + 171 = 166

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

x² + 166x - 855 = 0

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

(x - 5 ) (x + 171)

To summarize, since -5 and 171 multiply to -855 and add up 166, you know that the following is true:

x² + 166x - 855 = (x - 5 ) (x + 171)
