What two numbers multiply to 442 and add up to 223?

Here we answer the question: "What two numbers multiply to 442 and add up to 223?"

The answer to your question is:

2 and 221

Below we illustrate and prove that 2 and 221 multiply to 442 and add up to 223:

2 × 221 = 442
2 + 221 = 223

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

x² + 223x + 442 = 0

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

(x + 2 ) (x + 221)

To summarize, since 2 and 221 multiply to 442 and add up 223, you know that the following is true:

x² + 223x + 442 = (x + 2 ) (x + 221)
