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:

-7 and 21

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

-7 × 21 = -147
-7 + 21 = 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 - 7 ) (x + 21)

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

x² + 14x - 147 = (x - 7 ) (x + 21)
