What two numbers multiply to 422 and add up to 213?

Here we answer the question: "What two numbers multiply to 422 and add up to 213?"

The answer to your question is:

2 and 211

Below we illustrate and prove that 2 and 211 multiply to 422 and add up to 213:

2 × 211 = 422
2 + 211 = 213

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

x² + 213x + 422 = 0

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

(x + 2 ) (x + 211)

To summarize, since 2 and 211 multiply to 422 and add up 213, you know that the following is true:

x² + 213x + 422 = (x + 2 ) (x + 211)
