What two numbers multiply to -147 and add up to -14?

Here we answer the question: "What two numbers multiply to -147 and add up to -14?"

The answer to your question is:

-21 and 7

Below we illustrate and prove that -21 and 7 multiply to -147 and add up to -14:

-21 × 7 = -147
-21 + 7 = -14

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

x² - 14x - 147 = 0

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

(x - 21 ) (x + 7)

To summarize, since -21 and 7 multiply to -147 and add up -14, you know that the following is true:

x² - 14x - 147 = (x - 21 ) (x + 7)
