What two numbers multiply to 990 and add up to -203?

Here we answer the question: "What two numbers multiply to 990 and add up to -203?"

The answer to your question is:

-198 and -5

Below we illustrate and prove that -198 and -5 multiply to 990 and add up to -203:

-198 × -5 = 990
-198 + -5 = -203

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

x² - 203x + 990 = 0

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

(x - 198 ) (x - 5)

To summarize, since -198 and -5 multiply to 990 and add up -203, you know that the following is true:

x² - 203x + 990 = (x - 198 ) (x - 5)
