Here we answer the question: "What two numbers multiply to -826 and add up to 825?"
The answer to your question is:
-1 and 826
Below we illustrate and prove that -1 and 826 multiply to -826 and add up to 825:
-1 × 826 = -826
-1 + 826 = 825
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 825x - 826 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 826)
To summarize, since -1 and 826 multiply to -826 and add up 825, you know that the following is true:
x2 + 825x - 826 = (x - 1 ) (x + 826)
