What two numbers multiply to 488 and add up to -489?

Here we answer the question: "What two numbers multiply to 488 and add up to -489?"

The answer to your question is:

-488 and -1

Below we illustrate and prove that -488 and -1 multiply to 488 and add up to -489:

-488 × -1 = 488
-488 + -1 = -489

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

x² - 489x + 488 = 0

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

(x - 488 ) (x - 1)

To summarize, since -488 and -1 multiply to 488 and add up -489, you know that the following is true:

x² - 489x + 488 = (x - 488 ) (x - 1)
