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:

-66 and 3

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

-66 × 3 = -198
-66 + 3 = -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 - 66 ) (x + 3)

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

x² - 63x - 198 = (x - 66 ) (x + 3)
