What two numbers multiply to -144 and add up to 18?

Here we answer the question: "What two numbers multiply to -144 and add up to 18?"

The answer to your question is:

-6 and 24

Below we illustrate and prove that -6 and 24 multiply to -144 and add up to 18:

-6 × 24 = -144
-6 + 24 = 18

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

x² + 18x - 144 = 0

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

(x - 6 ) (x + 24)

To summarize, since -6 and 24 multiply to -144 and add up 18, you know that the following is true:

x² + 18x - 144 = (x - 6 ) (x + 24)
