What two numbers multiply to -168 and add up to 53?

Here we answer the question: "What two numbers multiply to -168 and add up to 53?"

The answer to your question is:

-3 and 56

Below we illustrate and prove that -3 and 56 multiply to -168 and add up to 53:

-3 × 56 = -168
-3 + 56 = 53

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

x² + 53x - 168 = 0

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

(x - 3 ) (x + 56)

To summarize, since -3 and 56 multiply to -168 and add up 53, you know that the following is true:

x² + 53x - 168 = (x - 3 ) (x + 56)
