Here we answer the question: "What two numbers multiply to -201 and add up to 200?"
The answer to your question is:
-1 and 201
Below we illustrate and prove that -1 and 201 multiply to -201 and add up to 200:
-1 × 201 = -201
-1 + 201 = 200
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 200x - 201 = 0
If so, the solution to factor the quadratic equation above is:
(x - 1 ) (x + 201)
To summarize, since -1 and 201 multiply to -201 and add up 200, you know that the following is true:
x2 + 200x - 201 = (x - 1 ) (x + 201)
