What two numbers multiply to -126 and add up to -5?

Here we answer the question: "What two numbers multiply to -126 and add up to -5?"

The answer to your question is:

-14 and 9

Below we illustrate and prove that -14 and 9 multiply to -126 and add up to -5:

-14 × 9 = -126
-14 + 9 = -5

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

x² - 5x - 126 = 0

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

(x - 14 ) (x + 9)

To summarize, since -14 and 9 multiply to -126 and add up -5, you know that the following is true:

x² - 5x - 126 = (x - 14 ) (x + 9)
