Here we answer the question: "What two numbers multiply to 644 and add up to -60?"
The answer to your question is:
-46 and -14
Below we illustrate and prove that -46 and -14 multiply to 644 and add up to -60:
-46 × -14 = 644
-46 + -14 = -60
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 60x + 644 = 0
If so, the solution to factor the quadratic equation above is:
(x - 46 ) (x - 14)
To summarize, since -46 and -14 multiply to 644 and add up -60, you know that the following is true:
x2 - 60x + 644 = (x - 46 ) (x - 14)
