What two numbers multiply to 637 and add up to 98?

Here we answer the question: "What two numbers multiply to 637 and add up to 98?"

The answer to your question is:

7 and 91

Below we illustrate and prove that 7 and 91 multiply to 637 and add up to 98:

7 × 91 = 637
7 + 91 = 98

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

x² + 98x + 637 = 0

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

(x + 7 ) (x + 91)

To summarize, since 7 and 91 multiply to 637 and add up 98, you know that the following is true:

x² + 98x + 637 = (x + 7 ) (x + 91)
