Here we answer the question: "What two numbers multiply to 688 and add up to -176?"
The answer to your question is:
-172 and -4
Below we illustrate and prove that -172 and -4 multiply to 688 and add up to -176:
-172 × -4 = 688
-172 + -4 = -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 - 172 ) (x - 4)
To summarize, since -172 and -4 multiply to 688 and add up -176, you know that the following is true:
x2 - 176x + 688 = (x - 172 ) (x - 4)
