What two numbers multiply to 648 and add up to -114?

Here we answer the question: "What two numbers multiply to 648 and add up to -114?"

The answer to your question is:

-108 and -6

Below we illustrate and prove that -108 and -6 multiply to 648 and add up to -114:

-108 × -6 = 648
-108 + -6 = -114

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

x² - 114x + 648 = 0

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

(x - 108 ) (x - 6)

To summarize, since -108 and -6 multiply to 648 and add up -114, you know that the following is true:

x² - 114x + 648 = (x - 108 ) (x - 6)
