What two numbers multiply to -864 and add up to -30?

Here we answer the question: "What two numbers multiply to -864 and add up to -30?"

The answer to your question is:

-48 and 18

Below we illustrate and prove that -48 and 18 multiply to -864 and add up to -30:

-48 × 18 = -864
-48 + 18 = -30

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

x² - 30x - 864 = 0

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

(x - 48 ) (x + 18)

To summarize, since -48 and 18 multiply to -864 and add up -30, you know that the following is true:

x² - 30x - 864 = (x - 48 ) (x + 18)
