What two numbers multiply to 800 and add up to 60?

Here we answer the question: "What two numbers multiply to 800 and add up to 60?"

The answer to your question is:

20 and 40

Below we illustrate and prove that 20 and 40 multiply to 800 and add up to 60:

20 × 40 = 800
20 + 40 = 60

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

x² + 60x + 800 = 0

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

(x + 20 ) (x + 40)

To summarize, since 20 and 40 multiply to 800 and add up 60, you know that the following is true:

x² + 60x + 800 = (x + 20 ) (x + 40)
