What two numbers multiply to 144 and add up to -24?

Here we answer the question: "What two numbers multiply to 144 and add up to -24?"

The answer to your question is:

-12 and -12

Below we illustrate and prove that -12 and -12 multiply to 144 and add up to -24:

-12 × -12 = 144
-12 + -12 = -24

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

x² - 24x + 144 = 0

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

(x - 12 ) (x - 12)

To summarize, since -12 and -12 multiply to 144 and add up -24, you know that the following is true:

x² - 24x + 144 = (x - 12 ) (x - 12)
