What two numbers multiply to 98 and add up to -99?

Here we answer the question: "What two numbers multiply to 98 and add up to -99?"

The answer to your question is:

-98 and -1

Below we illustrate and prove that -98 and -1 multiply to 98 and add up to -99:

-98 × -1 = 98
-98 + -1 = -99

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

x² - 99x + 98 = 0

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

(x - 98 ) (x - 1)

To summarize, since -98 and -1 multiply to 98 and add up -99, you know that the following is true:

x² - 99x + 98 = (x - 98 ) (x - 1)
