What two numbers multiply to -386 and add up to 385?

Here we answer the question: "What two numbers multiply to -386 and add up to 385?"

The answer to your question is:

-1 and 386

Below we illustrate and prove that -1 and 386 multiply to -386 and add up to 385:

-1 × 386 = -386
-1 + 386 = 385

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

x² + 385x - 386 = 0

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

(x - 1 ) (x + 386)

To summarize, since -1 and 386 multiply to -386 and add up 385, you know that the following is true:

x² + 385x - 386 = (x - 1 ) (x + 386)
