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:

2 and 10

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

2 × 10 = 20
2 + 10 = 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 + 2 ) (x + 10)

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

x² + 12x + 20 = (x + 2 ) (x + 10)
