What two numbers multiply to 636 and add up to 215?

Here we answer the question: "What two numbers multiply to 636 and add up to 215?"

The answer to your question is:

3 and 212

Below we illustrate and prove that 3 and 212 multiply to 636 and add up to 215:

3 × 212 = 636
3 + 212 = 215

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

x² + 215x + 636 = 0

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

(x + 3 ) (x + 212)

To summarize, since 3 and 212 multiply to 636 and add up 215, you know that the following is true:

x² + 215x + 636 = (x + 3 ) (x + 212)
