What two numbers multiply to 387 and add up to -388?

Here we answer the question: "What two numbers multiply to 387 and add up to -388?"

The answer to your question is:

-387 and -1

Below we illustrate and prove that -387 and -1 multiply to 387 and add up to -388:

-387 × -1 = 387
-387 + -1 = -388

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

x² - 388x + 387 = 0

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

(x - 387 ) (x - 1)

To summarize, since -387 and -1 multiply to 387 and add up -388, you know that the following is true:

x² - 388x + 387 = (x - 387 ) (x - 1)
