What two numbers multiply to -48 and add up to 13?

Here we answer the question: "What two numbers multiply to -48 and add up to 13?"

The answer to your question is:

-3 and 16

Below we illustrate and prove that -3 and 16 multiply to -48 and add up to 13:

-3 × 16 = -48
-3 + 16 = 13

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

x² + 13x - 48 = 0

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

(x - 3 ) (x + 16)

To summarize, since -3 and 16 multiply to -48 and add up 13, you know that the following is true:

x² + 13x - 48 = (x - 3 ) (x + 16)
