What two numbers multiply to 720 and add up to -54?

Here we answer the question: "What two numbers multiply to 720 and add up to -54?"

The answer to your question is:

-30 and -24

Below we illustrate and prove that -30 and -24 multiply to 720 and add up to -54:

-30 × -24 = 720
-30 + -24 = -54

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

x² - 54x + 720 = 0

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

(x - 30 ) (x - 24)

To summarize, since -30 and -24 multiply to 720 and add up -54, you know that the following is true:

x² - 54x + 720 = (x - 30 ) (x - 24)
