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:

1 and 98

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

1 × 98 = 98
1 + 98 = 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 + 1 ) (x + 98)

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

x² + 99x + 98 = (x + 1 ) (x + 98)
