What two numbers multiply to -489 and add up to 160?

Here we answer the question: "What two numbers multiply to -489 and add up to 160?"

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 160:

-3 × 163 = -489
-3 + 163 = 160

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

x² + 160x - 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 160, you know that the following is true:

x² + 160x - 489 = (x - 3 ) (x + 163)
