What two numbers multiply to -198 and add up to 63?

Here we answer the question: "What two numbers multiply to -198 and add up to 63?"

The answer to your question is:

-3 and 66

Below we illustrate and prove that -3 and 66 multiply to -198 and add up to 63:

-3 × 66 = -198
-3 + 66 = 63

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

x² + 63x - 198 = 0

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

(x - 3 ) (x + 66)

To summarize, since -3 and 66 multiply to -198 and add up 63, you know that the following is true:

x² + 63x - 198 = (x - 3 ) (x + 66)
