What two numbers multiply to 720 and add up to -126?

Here we answer the question: "What two numbers multiply to 720 and add up to -126?"

The answer to your question is:

-120 and -6

Below we illustrate and prove that -120 and -6 multiply to 720 and add up to -126:

-120 × -6 = 720
-120 + -6 = -126

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

x² - 126x + 720 = 0

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

(x - 120 ) (x - 6)

To summarize, since -120 and -6 multiply to 720 and add up -126, you know that the following is true:

x² - 126x + 720 = (x - 120 ) (x - 6)
