Here we answer the question: "What two numbers multiply to -626 and add up to 625?"
The answer to your question is:
-1 and 626
Below we illustrate and prove that -1 and 626 multiply to -626 and add up to 625:
-1 × 626 = -626
-1 + 626 = 625
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 625x - 626 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 626)
To summarize, since -1 and 626 multiply to -626 and add up 625, you know that the following is true:
x2 + 625x - 626 = (x - 1 ) (x + 626)
