What two numbers multiply to -836 and add up to 205?

Here we answer the question: "What two numbers multiply to -836 and add up to 205?"

The answer to your question is:

-4 and 209

Below we illustrate and prove that -4 and 209 multiply to -836 and add up to 205:

-4 × 209 = -836
-4 + 209 = 205

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

x² + 205x - 836 = 0

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

(x - 4 ) (x + 209)

To summarize, since -4 and 209 multiply to -836 and add up 205, you know that the following is true:

x² + 205x - 836 = (x - 4 ) (x + 209)
