What two numbers multiply to 684 and add up to -55?

Here we answer the question: "What two numbers multiply to 684 and add up to -55?"

The answer to your question is:

-36 and -19

Below we illustrate and prove that -36 and -19 multiply to 684 and add up to -55:

-36 × -19 = 684
-36 + -19 = -55

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

x² - 55x + 684 = 0

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

(x - 36 ) (x - 19)

To summarize, since -36 and -19 multiply to 684 and add up -55, you know that the following is true:

x² - 55x + 684 = (x - 36 ) (x - 19)
