Here we answer the question: "What two numbers multiply to -975 and add up to -14?"
The answer to your question is:
-39 and 25
Below we illustrate and prove that -39 and 25 multiply to -975 and add up to -14:
-39 × 25 = -975
-39 + 25 = -14
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 14x - 975 = 0
If so, the solution to factor the quadratic equation above is:
(x - 39 ) (x + 25)
To summarize, since -39 and 25 multiply to -975 and add up -14, you know that the following is true:
x2 - 14x - 975 = (x - 39 ) (x + 25)
