What two numbers multiply to 990 and add up to 101?

Here we answer the question: "What two numbers multiply to 990 and add up to 101?"

The answer to your question is:

11 and 90

Below we illustrate and prove that 11 and 90 multiply to 990 and add up to 101:

11 × 90 = 990
11 + 90 = 101

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

x² + 101x + 990 = 0

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

(x + 11 ) (x + 90)

To summarize, since 11 and 90 multiply to 990 and add up 101, you know that the following is true:

x² + 101x + 990 = (x + 11 ) (x + 90)
