What two numbers multiply to 18 and add up to -11?

Here we answer the question: "What two numbers multiply to 18 and add up to -11?"

The answer to your question is:

-9 and -2

Below we illustrate and prove that -9 and -2 multiply to 18 and add up to -11:

-9 × -2 = 18
-9 + -2 = -11

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

x² - 11x + 18 = 0

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

(x - 9 ) (x - 2)

To summarize, since -9 and -2 multiply to 18 and add up -11, you know that the following is true:

x² - 11x + 18 = (x - 9 ) (x - 2)
