What two numbers multiply to -988 and add up to 243?

Here we answer the question: "What two numbers multiply to -988 and add up to 243?"

The answer to your question is:

-4 and 247

Below we illustrate and prove that -4 and 247 multiply to -988 and add up to 243:

-4 × 247 = -988
-4 + 247 = 243

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

x² + 243x - 988 = 0

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

(x - 4 ) (x + 247)

To summarize, since -4 and 247 multiply to -988 and add up 243, you know that the following is true:

x² + 243x - 988 = (x - 4 ) (x + 247)
