What two numbers multiply to 135 and add up to -24?

Here we answer the question: "What two numbers multiply to 135 and add up to -24?"

The answer to your question is:

-15 and -9

Below we illustrate and prove that -15 and -9 multiply to 135 and add up to -24:

-15 × -9 = 135
-15 + -9 = -24

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

x² - 24x + 135 = 0

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

(x - 15 ) (x - 9)

To summarize, since -15 and -9 multiply to 135 and add up -24, you know that the following is true:

x² - 24x + 135 = (x - 15 ) (x - 9)
