What two numbers multiply to -72 and add up to -14?

Here we answer the question: "What two numbers multiply to -72 and add up to -14?"

The answer to your question is:

-18 and 4

Below we illustrate and prove that -18 and 4 multiply to -72 and add up to -14:

-18 × 4 = -72
-18 + 4 = -14

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

x² - 14x - 72 = 0

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

(x - 18 ) (x + 4)

To summarize, since -18 and 4 multiply to -72 and add up -14, you know that the following is true:

x² - 14x - 72 = (x - 18 ) (x + 4)
