What two numbers multiply to -852 and add up to 209?

Here we answer the question: "What two numbers multiply to -852 and add up to 209?"

The answer to your question is:

-4 and 213

Below we illustrate and prove that -4 and 213 multiply to -852 and add up to 209:

-4 × 213 = -852
-4 + 213 = 209

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

x² + 209x - 852 = 0

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

(x - 4 ) (x + 213)

To summarize, since -4 and 213 multiply to -852 and add up 209, you know that the following is true:

x² + 209x - 852 = (x - 4 ) (x + 213)
