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:

-91 and -7

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

-91 × -7 = 637
-91 + -7 = -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 - 91 ) (x - 7)

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

x² - 98x + 637 = (x - 91 ) (x - 7)
