Here we answer the question: "What two numbers multiply to 987 and add up to -988?"

The answer to your question is:

-987 and -1

Below we illustrate and prove that -987 and -1 multiply to 987 and add up to -988:

-987 × -1 = 987
-987 + -1 = -988

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

x² - 988x + 987 = 0

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

(x - 987 ) (x - 1)

To summarize, since -987 and -1 multiply to 987 and add up -988, you know that the following is true:

x² - 988x + 987 = (x - 987 ) (x - 1)
