What two numbers multiply to -478 and add up to 237?

Here we answer the question: "What two numbers multiply to -478 and add up to 237?"

The answer to your question is:

-2 and 239

Below we illustrate and prove that -2 and 239 multiply to -478 and add up to 237:

-2 × 239 = -478
-2 + 239 = 237

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

x² + 237x - 478 = 0

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

(x - 2 ) (x + 239)

To summarize, since -2 and 239 multiply to -478 and add up 237, you know that the following is true:

x² + 237x - 478 = (x - 2 ) (x + 239)
