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

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

The answer to your question is:

-1 and 488

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

-1 × 488 = -488
-1 + 488 = 487

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

x² + 487x - 488 = 0

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

(x - 1 ) (x + 488)

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

x² + 487x - 488 = (x - 1 ) (x + 488)
