What two numbers multiply to 242 and add up to -243?

Here we answer the question: "What two numbers multiply to 242 and add up to -243?"

The answer to your question is:

-242 and -1

Below we illustrate and prove that -242 and -1 multiply to 242 and add up to -243:

-242 × -1 = 242
-242 + -1 = -243

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

x² - 243x + 242 = 0

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

(x - 242 ) (x - 1)

To summarize, since -242 and -1 multiply to 242 and add up -243, you know that the following is true:

x² - 243x + 242 = (x - 242 ) (x - 1)
