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:

3 and 163

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

3 × 163 = 489
3 + 163 = 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 + 3 ) (x + 163)

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

x² + 166x + 489 = (x + 3 ) (x + 163)
