What two numbers multiply to 684 and add up to -69?




Here we answer the question: "What two numbers multiply to 684 and add up to -69?"

The answer to your question is:

-57 and -12


Below we illustrate and prove that -57 and -12 multiply to 684 and add up to -69:

-57 × -12 = 684
-57 + -12 = -69

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

x2 - 69x + 684 = 0

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

(x - 57 ) (x - 12)

To summarize, since -57 and -12 multiply to 684 and add up -69, you know that the following is true:

x2 - 69x + 684 = (x - 57 ) (x - 12)
