What two numbers multiply to 836 and add up to 213?

Here we answer the question: "What two numbers multiply to 836 and add up to 213?"

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 213:

4 × 209 = 836
4 + 209 = 213

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

x² + 213x + 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 213, you know that the following is true:

x² + 213x + 836 = (x + 4 ) (x + 209)
