What two numbers multiply to -247 and add up to 246?

Here we answer the question: "What two numbers multiply to -247 and add up to 246?"

The answer to your question is:

-1 and 247

Below we illustrate and prove that -1 and 247 multiply to -247 and add up to 246:

-1 × 247 = -247
-1 + 247 = 246

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

x² + 246x - 247 = 0

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

(x - 1 ) (x + 247)

To summarize, since -1 and 247 multiply to -247 and add up 246, you know that the following is true:

x² + 246x - 247 = (x - 1 ) (x + 247)
