Here we answer the question: "What two numbers multiply to -975 and add up to 50?"
The answer to your question is:
-15 and 65
Below we illustrate and prove that -15 and 65 multiply to -975 and add up to 50:
-15 × 65 = -975
-15 + 65 = 50
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 50x - 975 = 0
If so, the solution to factor the quadratic equation above is:
(x - 15 ) (x + 65)
To summarize, since -15 and 65 multiply to -975 and add up 50, you know that the following is true:
x2 + 50x - 975 = (x - 15 ) (x + 65)
