What two numbers multiply to -438 and add up to 437?

Here we answer the question: "What two numbers multiply to -438 and add up to 437?"

The answer to your question is:

-1 and 438

Below we illustrate and prove that -1 and 438 multiply to -438 and add up to 437:

-1 × 438 = -438
-1 + 438 = 437

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

x² + 437x - 438 = 0

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

(x - 1 ) (x + 438)

To summarize, since -1 and 438 multiply to -438 and add up 437, you know that the following is true:

x² + 437x - 438 = (x - 1 ) (x + 438)
