What two numbers multiply to 165 and add up to -166?

Here we answer the question: "What two numbers multiply to 165 and add up to -166?"

The answer to your question is:

-165 and -1

Below we illustrate and prove that -165 and -1 multiply to 165 and add up to -166:

-165 × -1 = 165
-165 + -1 = -166

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

x² - 166x + 165 = 0

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

(x - 165 ) (x - 1)

To summarize, since -165 and -1 multiply to 165 and add up -166, you know that the following is true:

x² - 166x + 165 = (x - 165 ) (x - 1)
