What two numbers multiply to -663 and add up to 38?

Here we answer the question: "What two numbers multiply to -663 and add up to 38?"

The answer to your question is:

-13 and 51

Below we illustrate and prove that -13 and 51 multiply to -663 and add up to 38:

-13 × 51 = -663
-13 + 51 = 38

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

x² + 38x - 663 = 0

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

(x - 13 ) (x + 51)

To summarize, since -13 and 51 multiply to -663 and add up 38, you know that the following is true:

x² + 38x - 663 = (x - 13 ) (x + 51)
