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

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

The answer to your question is:

-243 and 1

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

-243 × 1 = -243
-243 + 1 = -242

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

x² - 242x - 243 = 0

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

(x - 243 ) (x + 1)

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

x² - 242x - 243 = (x - 243 ) (x + 1)
