What two numbers multiply to 216 and add up to 42?

Here we answer the question: "What two numbers multiply to 216 and add up to 42?"

The answer to your question is:

6 and 36

Below we illustrate and prove that 6 and 36 multiply to 216 and add up to 42:

6 × 36 = 216
6 + 36 = 42

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

x² + 42x + 216 = 0

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

(x + 6 ) (x + 36)

To summarize, since 6 and 36 multiply to 216 and add up 42, you know that the following is true:

x² + 42x + 216 = (x + 6 ) (x + 36)
