What two numbers multiply to 36 and add up to -20?

Here we answer the question: "What two numbers multiply to 36 and add up to -20?"

The answer to your question is:

-18 and -2

Below we illustrate and prove that -18 and -2 multiply to 36 and add up to -20:

-18 × -2 = 36
-18 + -2 = -20

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

x² - 20x + 36 = 0

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

(x - 18 ) (x - 2)

To summarize, since -18 and -2 multiply to 36 and add up -20, you know that the following is true:

x² - 20x + 36 = (x - 18 ) (x - 2)
