What two numbers multiply to 416 and add up to 210?

Here we answer the question: "What two numbers multiply to 416 and add up to 210?"

The answer to your question is:

2 and 208

Below we illustrate and prove that 2 and 208 multiply to 416 and add up to 210:

2 × 208 = 416
2 + 208 = 210

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

x² + 210x + 416 = 0

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

(x + 2 ) (x + 208)

To summarize, since 2 and 208 multiply to 416 and add up 210, you know that the following is true:

x² + 210x + 416 = (x + 2 ) (x + 208)
