What two numbers multiply to -212 and add up to 211?

Here we answer the question: "What two numbers multiply to -212 and add up to 211?"

The answer to your question is:

-1 and 212

Below we illustrate and prove that -1 and 212 multiply to -212 and add up to 211:

-1 × 212 = -212
-1 + 212 = 211

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

x² + 211x - 212 = 0

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

(x - 1 ) (x + 212)

To summarize, since -1 and 212 multiply to -212 and add up 211, you know that the following is true:

x² + 211x - 212 = (x - 1 ) (x + 212)
