What two numbers multiply to 824 and add up to 210?

Here we answer the question: "What two numbers multiply to 824 and add up to 210?"

The answer to your question is:

4 and 206

Below we illustrate and prove that 4 and 206 multiply to 824 and add up to 210:

4 × 206 = 824
4 + 206 = 210

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

x² + 210x + 824 = 0

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

(x + 4 ) (x + 206)

To summarize, since 4 and 206 multiply to 824 and add up 210, you know that the following is true:

x² + 210x + 824 = (x + 4 ) (x + 206)
