What two numbers multiply to 247 and add up to -248?

Here we answer the question: "What two numbers multiply to 247 and add up to -248?"

The answer to your question is:

-247 and -1

Below we illustrate and prove that -247 and -1 multiply to 247 and add up to -248:

-247 × -1 = 247
-247 + -1 = -248

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

x² - 248x + 247 = 0

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

(x - 247 ) (x - 1)

To summarize, since -247 and -1 multiply to 247 and add up -248, you know that the following is true:

x² - 248x + 247 = (x - 247 ) (x - 1)
