What two numbers multiply to 487 and add up to -488?

Here we answer the question: "What two numbers multiply to 487 and add up to -488?"

The answer to your question is:

-487 and -1

Below we illustrate and prove that -487 and -1 multiply to 487 and add up to -488:

-487 × -1 = 487
-487 + -1 = -488

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

x² - 488x + 487 = 0

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

(x - 487 ) (x - 1)

To summarize, since -487 and -1 multiply to 487 and add up -488, you know that the following is true:

x² - 488x + 487 = (x - 487 ) (x - 1)
