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:

-51 and 13


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

-51 × 13 = -663
-51 + 13 = -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 - 51 ) (x + 13)

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

x2 - 38x - 663 = (x - 51 ) (x + 13)
