What two numbers multiply to 624 and add up to -55?

Here we answer the question: "What two numbers multiply to 624 and add up to -55?"

The answer to your question is:

-39 and -16

Below we illustrate and prove that -39 and -16 multiply to 624 and add up to -55:

-39 × -16 = 624
-39 + -16 = -55

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

x² - 55x + 624 = 0

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

(x - 39 ) (x - 16)

To summarize, since -39 and -16 multiply to 624 and add up -55, you know that the following is true:

x² - 55x + 624 = (x - 39 ) (x - 16)
