Here we answer the question: "What two numbers multiply to -975 and add up to 190?"
The answer to your question is:
-5 and 195
Below we illustrate and prove that -5 and 195 multiply to -975 and add up to 190:
-5 × 195 = -975
-5 + 195 = 190
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 190x - 975 = 0
If so, the solution to factor the quadratic equation above is:
(x - 5 ) (x + 195)
To summarize, since -5 and 195 multiply to -975 and add up 190, you know that the following is true:
x2 + 190x - 975 = (x - 5 ) (x + 195)
