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:

5 and 198

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

5 × 198 = 990
5 + 198 = 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 + 5 ) (x + 198)

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

x² + 203x + 990 = (x + 5 ) (x + 198)
