What two numbers multiply to -636 and add up to 209?

Here we answer the question: "What two numbers multiply to -636 and add up to 209?"

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 209:

-3 × 212 = -636
-3 + 212 = 209

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

x² + 209x - 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 209, you know that the following is true:

x² + 209x - 636 = (x - 3 ) (x + 212)
