What two numbers multiply to 489 and add up to -166?

Here we answer the question: "What two numbers multiply to 489 and add up to -166?"

The answer to your question is:

-163 and -3

Below we illustrate and prove that -163 and -3 multiply to 489 and add up to -166:

-163 × -3 = 489
-163 + -3 = -166

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

x² - 166x + 489 = 0

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

(x - 163 ) (x - 3)

To summarize, since -163 and -3 multiply to 489 and add up -166, you know that the following is true:

x² - 166x + 489 = (x - 163 ) (x - 3)
