What two numbers multiply to -864 and add up to 138?

Here we answer the question: "What two numbers multiply to -864 and add up to 138?"

The answer to your question is:

-6 and 144

Below we illustrate and prove that -6 and 144 multiply to -864 and add up to 138:

-6 × 144 = -864
-6 + 144 = 138

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

x² + 138x - 864 = 0

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

(x - 6 ) (x + 144)

To summarize, since -6 and 144 multiply to -864 and add up 138, you know that the following is true:

x² + 138x - 864 = (x - 6 ) (x + 144)
