What two numbers multiply to 320 and add up to 36?

Here we answer the question: "What two numbers multiply to 320 and add up to 36?"

The answer to your question is:

16 and 20

Below we illustrate and prove that 16 and 20 multiply to 320 and add up to 36:

16 × 20 = 320
16 + 20 = 36

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

x² + 36x + 320 = 0

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

(x + 16 ) (x + 20)

To summarize, since 16 and 20 multiply to 320 and add up 36, you know that the following is true:

x² + 36x + 320 = (x + 16 ) (x + 20)
