Here we answer the question: "What two numbers multiply to 688 and add up to 176?"

The answer to your question is:

4 and 172

Below we illustrate and prove that 4 and 172 multiply to 688 and add up to 176:

4 × 172 = 688
4 + 172 = 176

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

x² + 176x + 688 = 0

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

(x + 4 ) (x + 172)

To summarize, since 4 and 172 multiply to 688 and add up 176, you know that the following is true:

x² + 176x + 688 = (x + 4 ) (x + 172)
