Here we answer the question: "What two numbers multiply to 988 and add up to -989?"

The answer to your question is:

-988 and -1

Below we illustrate and prove that -988 and -1 multiply to 988 and add up to -989:

-988 × -1 = 988
-988 + -1 = -989

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

x² - 989x + 988 = 0

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

(x - 988 ) (x - 1)

To summarize, since -988 and -1 multiply to 988 and add up -989, you know that the following is true:

x² - 989x + 988 = (x - 988 ) (x - 1)
