What two numbers multiply to 20 and add up to -12?

Here we answer the question: "What two numbers multiply to 20 and add up to -12?"

The answer to your question is:

-10 and -2

Below we illustrate and prove that -10 and -2 multiply to 20 and add up to -12:

-10 × -2 = 20
-10 + -2 = -12

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

x² - 12x + 20 = 0

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

(x - 10 ) (x - 2)

To summarize, since -10 and -2 multiply to 20 and add up -12, you know that the following is true:

x² - 12x + 20 = (x - 10 ) (x - 2)
