What two numbers multiply to -838 and add up to 837?

Here we answer the question: "What two numbers multiply to -838 and add up to 837?"

The answer to your question is:

-1 and 838

Below we illustrate and prove that -1 and 838 multiply to -838 and add up to 837:

-1 × 838 = -838
-1 + 838 = 837

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

x² + 837x - 838 = 0

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

(x - 1 ) (x + 838)

To summarize, since -1 and 838 multiply to -838 and add up 837, you know that the following is true:

x² + 837x - 838 = (x - 1 ) (x + 838)
