Here we answer the question: "What two numbers multiply to 627 and add up to -68?"
The answer to your question is:
-57 and -11
Below we illustrate and prove that -57 and -11 multiply to 627 and add up to -68:
-57 × -11 = 627
-57 + -11 = -68
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 68x + 627 = 0
If so, the solution to factor the quadratic equation above is:
(x - 57 ) (x - 11)
To summarize, since -57 and -11 multiply to 627 and add up -68, you know that the following is true:
x2 - 68x + 627 = (x - 57 ) (x - 11)
